In Spiderman 3, a large portion of New York city is aware of Spiderman and Mary Jane's upside down kiss from Spiderman 1. An entire crowd urges Peter Parker to recreate the upside-down kiss with Gwen. However, no-one saw Spiderman and Mary Jane kiss in the first place. Although the 'upside-down kiss' scene is a memorable cinematic moment, it occurred in an abandoned alley. [They're not urging him to "recreate" anything; they just want Spider-Man and Gwen to kiss. He just happens to be upside down at the time. There is no indication whatsoever that anyone knows about his and Mary Jane's kiss.] Corrected by Phixius

In the scene where Harry is lying in the hospital bed, his shirt is open enough that you can see his nipple. There is a cut to Peter who speaks, and when the camera goes back to Harry, his nipple is covered up. [This mistake has already been listed.]

During Flint's final flashback of killing Uncle Ben, there is a tear rolling down Uncle Ben's face when he gets shot. Then the camera turns to Flint, and then back to Uncle Ben falling, and there is no tear on his face. [Because it continued rolling down his face, even while the camera was on Flint, and subsequently rolled off his face.] Corrected by Phixius

Near the end when Flint Marko turns himself into a cloud of sand, it flies away into the city. When it flies behind the huge building, you can determine the sheer size of the sand cloud. But the sand cloud only came from his own body and didn't 'borrow' any nearby sand, so the volume of sand shouldn't have been so large. [Sandman can change his density as well as his size and shape. Tightly packed sand doesn't take up much space; but when spread out there appears to be much more than one might have thought.] Corrected by Phixius

When Spiderman is going to chase Sandman after the bank robbery he rip out the sewerage cover with some concrete around it, a few seconds later when Spiderman jumps through this hole the concrete edges are totally intact. [After ripping the concrete out, you never see the outside edges again. You can see the inside, which is a large metal manhole, but this is undamaged as it was not attached to the concrete. Hence, not a mistake.]

In the scene where Peter goes to tell his aunt he is going to marry MJ, she is serving him tea and goes to get milk out of the fridge. It happens fast, but if you watch, she actually pulls Tropicana Orange juice out, then the next shot, she is shown pouring milk for the tea, there is no orange juice on the table or any need for it in tea. [No, she has Tuscan milk all the time.] Corrected by Sacha

(Everything I'm describing is a shadow) In the scene where Sandman first meets Venom, we see the shadow of Venom on a wall get hit by a garbage can that Sandman is holding. Sandman then holds the garbage can behind his back, and if you look closely the garbage can literally disappears. [I believe he whacked him with a self-produced sand mallet. He can whack people with a stream of sand, so why not make a weapon out of it?]

During the "runaway crane" incident, Spider-Man comes to save the crane driver and stop the crane. Gwen is being knocked out of a building, he saves her and then swings off, never at all stopping the crane, or saving the driver. [By the time he was done rescuing Gwen, the power to the block would be cut off, just like Cpt. Stacy ordered earlier. The crane would not be a threat anymore, and the driver could easily be taken to safety.] Corrected by Twotall

Eddie Brock's Bad Teeth. The symbiote is supposed to accentuate the host's bad characteristics. At the end of the movie, when Venom and Spiderman are fighting and just before Eddie Brock is killed, we see that he has bad teeth. When the symbiote pulls back from his face, we can see that his natural teeth are jagged and worn, hence it makes sense that the symbiote would accentuate this effect and give the Venom character vicious razor-sharp teeth like those of a shark. However, if you look at Eddie Brock in any previous scenes, he does not have bad teeth at all, in fact he has quite good teeth. Seems as if the bad teeth were an afterthought added midway through production. [It is never stated that the symbiote accentuates its hosts undesirable characteristics; only that it "amplifies aggression." Eddie's teeth are "bad" because the symbiote is a part of him, whereas it merely covered Peter; Eddie let it take him over completely. This is why the symbiote has it's natural appearance when Eddie appears as Venom, complete with it's own oral orifice.] Corrected by Phixius

When Flint is running from the cops, he hops a fence and all of the sudden he is in some special molecule testing facility. Where are the security guards? [They vacated the area for safety because the test was about to begin. There is a fence to deter trespassers, and it's doubtful there's a whole lot of foot traffic through there anyway. The odds of someone breaking in at that particular moment were pretty slim.] Corrected by Phixius

In the scene where Peter Parker is in the resturant where Mary Jane is singing he is sitting down having a drink and in the background you see Willem Defoe as an extra in the scene. [It has been stated several times that this is not Willem Dafoe, and if you look close, it is obvious the man in question looks considerably younger and different than Dafoe.]

The photograph of Mary Jane next to Peter's police scanner is the picture he took of her at the science exhibit in the first Spider-Man movie. [Pointing out the obvious doesn't make it trivia.] Corrected by Phixius

At the start of the film, when Peter is explaining to Mary Jane about how sound waves travel, his explanation ends up being applicable to the concept of how the symbiote can be defeated. [This is considered "Foreshadowing", not trivia.]

In the scene when Eddie enters J Jameson's room without permission to show him the Spider-man photos you can see Miss Brant pick up her phone in frustration. But in the next shot you can see Miss Brant looking inside through the glass. [So she decided not to call Jonah, and just watch to see how he reacted to Brock's intrusion.] Corrected by Phixius

When Spiderman is fighting Venom at the start of the battle to save MJ, his mask is removed and thrown from the building. Within 1 minute, it's magically reappeared on his head. [No, he is thrown to the ground, conveniently landing next to his mask, at which point he puts it back on.] Corrected by Phixius

When the police officer throws the tarp from the top of the sand truck, the entire tarp falls off. Yes, this had to work to sell the sequence, but there is no way someone could lift the entire tarp off of that long truck, especially at the angle and the force with with he drew the tarp. Look closely, you can tell that a wire connected to the middle of the tarp was used to lift it from the truck bed and was deleted digitally later. [We are not supposed to believe he took it off completely. He lifts it up, and the wind picks it up the rest of the way.]

When Flint Marco is walking downing the street just after turning into Sandman, two cops notice him and give chase. He runs behind a truck and disappears. When the cops get there, there are 5 or 6 people walking by. From their point of view they would of seen where he went, but no one seems dumbfounded or shocked that a man just turned to sand and slid into the back of a truck. The tarp on the truck was tied down on all sides, so he couldn't have jumped in as a man. [There is no reason that Flint could not have rolled under the truck, then turned to sand, as opposed as just turning to sand. The movie even shows that the sand is still entering the truck when the cops arrive.]

When the sandman is in his house you see him breaking up the bread ready to eat, as he leaves through the window the bread is a whole loaf again. [He puts the two halves of the bread together on the table. The loaf isn't whole again, but we can't see the split since the way the loaf is placed.]

When MJ goes over to Harry's place for lunch, Harry is seen putting butter and what looks like peppers into the pan. They then start dancing until MJ says "The butter!" The next shot shows the pan with only butter in in - no peppers. [Harry puts red peppers in a stainless steel skillet and puts the butter in a black non-stick pan. When she yells,"The butter!," they then add eggs to the black skillet with the butter. The Butter and Peppers were never in the same pan.] Corrected by David Little

When Aunt May comes to visit Peter at his apartment, she is easily able to open the door that has taken Pete's strength to open from the outside every other time throughout the film. [She doesn't open the door, she knocks and Peter lets her in. He also breaks off the doorknob in this scene because the door is stuck.] Corrected by Nick Bylsma
