Back to the Future

Corrected entry: When Doc is on the clock tower in 1955 during the storm, a closeup of his feet is shown. He is wearing shoes with velcro straps in this shot. Velcro did not yet exist in 1955, and Doc had not yet traveled into the future.

Correction: The concept behind Velcro was conceived in 1941, the idea was submitted for a patent in 1951, and the patent was granted in 1955. Not impossible that Dr. Emmett Brown, a member of a wealthy family and fellow inventor, could acquire some.

Corrected entry: Even with Marty's brief instructions, it is near impossible that each backing band member (each, and as a whole) could have pulled off a near perfect rendition of Johnny B. Goode, not ever having rehearsed, known or heard the song, etc.

Correction: 1. It is NOT a perfect rendition. 2. "Near impossible" is not impossible. 3. This posting renders every musical ever made impossible.

2

Also, Johnny B Good is a three-chord song. Any musician, especially one in a professional band, could follow the pattern, knowing the key.

Corrected entry: Anyone else find it ironic that Einstein the dog was the world's first time traveler, while the real Einstein was the one who said that time travel is impossible?

Correction: Part of the "strange" world that Einstein explained in 1905 in his theory of relativity is that time and space are joined in our universe as a four-dimensional fabric known as space-time. Stranger yet is the concept that both space and time warp as mass or speed is increased. Einstein actually proved that time travel was theoretically possible, then spent the rest of his life trying to disprove it.

Corrected entry: Wouldn't Marty's parents and Biff Tannen be amazed and freaked out that their son Marty is identical to Calvin, the kid that played a major part in all their lives, and who they would definitely remember?

ShooterMcGavin34

Correction: It's 30 years later, I doubt they remember a guy who they only knew for a few days back when they were teenagers well enough to recognise him as Marty.

Corrected entry: In the scene where Marty is playing Johnny B. Goode, and someone cuts into George and Lorraine's dance, Marty starts disappearing. Then he comes back, pushes the guy down, and kisses Lorraine, resulting in Marty reappearing. But George did that on his own, without Marty interfering, so why should he have disappeared in the first place? He was always going to come back and assert himself - it's not like the timeline was being changed.

Correction: According to the films, the future is never set. For instance, in the third film, at first it's Doc's name on the tombstone, then no one's name, then Marty's name starts to appear, then finally the tombstone disappears altogether. This happens in response to how Doc and Marty act and make decisions. The same idea applies to the dance- when it looks like George is just going to walk away, Marty's existence is in danger, but when George changes his mind and returns to Lorraine, the future has changed, and Marty's existence is secure.

Corrected entry: When Marty travels to 1955 it's about 1:35 am but when he is heading downtown the sun is rising.

oswal13

Correction: If you look at the time readouts, Marty travels to Nov. 12, 1955 at around 6 am. What time it was at the moment didn't matter.

Corrected entry: Early in the film, Mr. Strickland tells Marty that he is a slacker and that he reminds him of his father because he was a slacker too. However, it is extremely unlikely that Mr. Stickland should even remember who George McFly is. How many school administrators can remember some random student from 30 years prior? It would make more sense if he was George's teacher because teachers can have a close relationship with their students, but as a school administrator, there have literally been tens of thousands of students under his watch during his 30 year tenure at Hill Valley High School. It's not as if George ever did anything to stand out. He was not a star athlete or a valedictorian and never did anything noteworthy in his life in the original timeline. He was not a troublemaker either, so it's not as if he would have spent a lot of time in Strickland's office. He should have been a nameless face in the crowd as far as Strickland was concerned, so hard to believe he would still remember such a random person after 30 years. I have only been out of high school for 13 years myself and if I ran into my old principal in the street tomorrow, I can guarantee that he wouldn't be able to remember me to save his life.

calidude

Correction: George did do something to stand out. He did nothing! Strickland hates slackers and clearly remembers them. One of my guidance counselors in jr. high was my father's guidance counselor and knew exactly who my father was based on my last name alone 21 years later. Some people just have very good memories for names and faces.

Corrected entry: After Marty returns to the present, he wakes up in his room that is identical to the beginning of the movie, however the rest of the house i.e the living has changed and is more modern.

Waldo Gonzalez

Correction: That merely tells us that Marty was more or less the same in both timelines, having similar tastes.

Which wouldn't happen. Because with loving, successful and self confident parents, there's no way a kid turns up just the same as with goofy, drunk, and pushovers parents.

Unlikely, but not impossible and therefore, not a mistake.

oldbaldyone

Corrected entry: Mayor Red Thomas in the 1950s based on his picture, looks to be around age 50. However, in 1985, when he is a bum, he still looks about the same age, even though he should be around 80 years old now. Granted, some people age better than others, but it is doubtful that an old man living on the streets would even survive for very long, let alone age gracefully.

calidude

Correction: You are assuming Red has lived on the streets for a long time. We have absolutely no information about how long he has been a bum; he could just as well be a youngish-looking 80-year-old who just recently suffered a decline in fortune and became homeless as a result.

Twotall

Red the homeless guy is not former mayor Red Thomas. Bob gale said that Fox improvised the name on the day.

Corrected entry: When Marty is trying to prove his futureness to Doc, he says that his sister was in the class of 1984 and then shows Doc a picture. Whenever the picture is shown however, the shirt says class of '81.

Correction: There's a vertical fold in her sweatshirt causing the '4' to be compressed so it looks like a '1' if you don't look too closely.

Corrected entry: This one is tricky but important in view of Doc's concern about doing anything that will alter the future. The lightning rod on the clock tower would have been connected to ground with a thick cable. Doc would have had to disconnect this cable to allow the current from the lightning to flow into his cable instead and hence to the time machine. We now know that a lightning strike is a result of a complex interaction of electric potentials between charges in a cloud and charges in the ground below. By disconnecting this grounding cable this interaction would have been disrupted, causing the lightning to strike at a different time or strike a different object on the ground.

Correction: If you touch a lightning rod while lightning strikes it, you will still get electrocuted. So, just like the energy would travel into your body, it traveled through Doc's cable. No need to disconnect the ground. If grounding a power source kept it from charging any thing else, no electrical appliance would ever function.

Corrected entry: When Marty travels back to 1955 the DeLorean first strikes a scarecrow, then drives at high speed into a barn and finally crashes through the barn door to escape. Later, when it returns to 1985, it crashes into a movie theatre front before it can stop. After all this mayhem the DeLorean doesn't have as much as a scratch on its nose.

Correction: That's because the entire body of every DMC DeLorean is made out of stainless steel, not fiberglass.

Corrected entry: After Marty returns to 1985, he discovers that he now has the new Toyota truck he wanted, while the rest of his family is forced to share one car. Why would Marty, the youngest of the siblings, who is still in high school, have his own brand new truck while his older siblings and both parents have to share one other vehicle?

calidude

Correction: We only see one vehicle other than the truck, this does not mean it is the only other vehicle. We only know that Marty's older brother uses the car to go to work.

Corrected entry: After Marty reunites his parents, he and his siblings all reappear in the photo and all is well. However, in order for Marty and his brother and sister to exist again, it would mean that Marty's parents would have to have sex at the exact same moment all three times to conceive them. Even if they were a few seconds off, it wouldn't be the exact same three kids. Similar maybe, but not exact. Now that George is more successful, he will be doing many things differently in his life so the chances of him and Lorraine having sex at the exact same millisecond all three times to have those exact three kids is beyond astronomical.

calidude

Correction: This is purely speculative. There is no way anyone (other than the filmmakers) can say what "should" have happened in the altered timeline. The odds may be astronomical, but the odds are certainly better than the odds of a plutonium-powered, time-travelling Delorean being invented.

Corrected entry: When Marty is trying to prove to Doc that he is from the future, he shows him his driver's license and the photo of himself and his siblings. Doc immediately dismisses them both. Doesn't Doc notice that the quality of the color in the photos is much better than any color film that existed in the 1950's? Wouldn't that grab his attention?

calidude

Correction: If he actually took the time to examine it, maybe. Think about it, if someone walked up and told you he was from the future and showed you a document to prove it, would you believe him and examine it or humor the weirdo and get away as quick as you could?

Corrected entry: When older Lorraine is talking about when she first met Marty's dad, the words VODKA on the vodka bottle are reversed therefore the shot was flipped.

sarahmb2

Correction: "VODKA" (at the bottom of the label) is not spelled backwards. I think you're confusing it with the brand of vodka, POPOV. Only the last few letters are visible in the shot. ("-OV").

Corrected entry: When Doc is having the DeLorean do the burn out to get the car up to speed, the car is spinning its wheels up to 65 mph and Doc releases the brake. Now the car takes off, but the car would lose most of the speed the tires had built up as it is starting from essentially a dead stop even though the speedometer still shows 65 mph. Think of it this way, the back tires may be moving at 65 mph but the front tires are not. There is no physically possible way for a car to jump from 0 to 65 mph instantaneously using only its tires no matter how fast they were rotating. Even an F/A-18 needs a catapult to get that kind of speed so quickly. (00:21:35)

StopNGo & Girls

Correction: If the speedometer was hooked up in such a way as to show 65MPH as the speed before the brake was released, it would still show it afterward. The car was never going 65, true, but the tires were telling the speedometer it was. For whatever reason this is how Doc wired it all together. The tires wouldn't slow down suddenly just because the brake was let up, they'd continue to skid until the car's speed matched their own.

Corrected entry: When Loraine tries to kiss Marty in the car and he pulls away, she asks if something is wrong, but instead of calling him "Calvin" (as in Calvin Klein) she calls him "Marty."

Correction: When Marty first met her, and she thought his name was Calvin Klein, he told her his friends called him Marty. She referred to him as Calvin and then Marty in the scene in Doc's garage, and she calls him Marty in their last scene before he goes back to 1985. Clearly she's getting used to calling him Marty.

Corrected entry: If everything that happens in the past, determines what happens in the future,and there in between, then wouldn't it make more sense for the picture of the family, when it starts to come back, to have them dressed differently? Such is the case when they are in the new family scene, when they come back.

Correction: This is a question, not a mistake. There's no reason why they couldn't be wearing the same clothes in the altered timeline.

Corrected entry: When Marty is plugging his guitar in to the mega amp, the amplifier end of the cable is stereo (like you would use for headphones) and the guitar end is the correct mono connector.

Lunchbox

Correction: This is obviously something Doc Brown built himself, not an "off-the-shelf" item. For whatever reason he wanted, needed, or settled on a stereo connection in the amp.

Back to the Future mistake picture

Continuity mistake: When we first see the machine in action, the travel is shown from three different angles. In the second, a line of fire passes directly between Doc's legs, but in the third angle, they pass to the left of both of his legs. (00:21:00)

Dr. Emmett Brown: Don't worry. As long as you hit that wire with the connecting hook at precisely 88mph the instant the lightning strikes the tower... Everything will be fine.

More quotes from Back to the Future

Trivia: The farm where Marty arrives in 1955 belongs to a man called Peabody, and he calls his son Sherman; the names are a tribute to "Sherman and Mr. Peabody," two cartoon time travellers from a 1960s American TV show.

Question: What does the saying "Why don't you make like a tree, and get out of here", mean?

Answer: It's a way of saying "scram" or "get lost." But Biff is so dim, he doesn't realize he's saying it wrong; the expression is "make like a tree and leaf", with the joke being that "leaf" is meant to sound like "leave."
