Corrected entry: The Gremlins die, or at the very least are stopped in their tracks, if exposed to bright light, and we see in a couple of scenes that a flash from a Polaroid is sufficient for this. How then are the many Gremlins OK when sat within the range of a very powerful projection light that is projecting Snow White onto the screen in the cinema?
Corrected entry: When the gremlins are attacking Billy's mom in the kitchen, the kitchen is well lit with a window that allows sunlight into the room. If bright light kills gremlins, wouldn't they die when they enter the kitchen?
Corrected entry: When Billy is talking to the Sheriff and his Deputy, he explains what the creatures are, and shows them Gizmo. The cops don't take Billy's story seriously and even mock him, even after the phone call about the Futterman's Snowplough "accident." Why didn't Billy simply tell the Sheriff about the dead Teacher or get them to call the Dr where Billy left his injured mother? The mere mention of a dead body should have to be investigated by the police, and the word of a local respected Dr should also be enough to back up Billy's story and give him the help he's need to stop the Gremlins.
Corrected entry: When Billy is having car trouble before work, he opens the bonnet and a lot of steam rises from the engine. VW Beetles have air cooled engines, which do not contain water to create steam.
Corrected entry: When the "Whistle While You Work" sequence is shown from "Snow White" the music is wrong. It sounds like music from the film, but it's not from that particular song.
Corrected entry: At the very end of the film, just before the credits start rolling, the clouds in the sky can be seen to move behind the moon - this is impossible.
Corrected entry: During the scene when the gremlin tampers with the brake cable on the police car, the car then pulls off down the street and you can see the brake lights come on as the car slows up to go round a sharp corner. (01:07:00 - 01:07:55)
Corrected entry: When the policemen get back into their car, the gremlin has let the fluid out of the brakes. The policemen drive off, but can't stop. Remarkably however they seem to have no trouble in the next scene, stopping the car and turning left.
Corrected entry: When they enter the department store at the end of the film, it is dark outside, so where did the strong sunlight that killed Stripe come from?
Corrected entry: When they're at the cinema the movie "Snow White" starts up during the "Heigh Ho" sequence. Later, while Billy and Kate are sneaking around, it's the "Whistle While you Work" sequence which comes before "Heigh Ho", not after.
Corrected entry: When Mr. Peltzer is telling his wife he can't come home for Christmas, you can see Robbie the Robot in the background, he was used in many movies, such as a movie in the 1950's called "Forbidden Planet". You can also hear him say, "Would 60 gallons be sufficient", which was a line he said in Forbidden Planet.
Corrected entry: How did the Gremlins know the lyrics for "Heigh Ho"? They hear "heigh ho" and then sing "it's home from work we go" without having heard the line sung in the film.
Corrected entry: In the beginning when Billy is late for work, he puts out his name plaque and it is upside down. A few moments later, it is right side up.
Corrected entry: Gremlins have three fingers, but there are four sratches on Billy's shirt when Stripe claws him.
Corrected entry: Given they are in the middle of winter with a fresh snowfall on the ground - you don't see anyone's cold breath outside in ANY scene and you should.
Corrected entry: If you watch the scene where the Gremlin is throwing plates at Billy's mother in slow motion, on the last plate thrown, you will see that the plate is not in the gremlin's hand, rather it comes up from behind the gremlin.
