Other mistake: Beethoven didn't seem fussed nor resentful of Napoleon being part of the group. Historically he temporarily admired him and wrote the Third Symphony inspired by Napoleon's ideals of Europe's new hope of enlightenment but later despised him after he crowned himself Emperor of France in 1804 and furiously scribbled out his name off the title page of his Third Symphony and named it Eroica which he originally titled it as "Bonaparte Symphony" due to his former admiration of Napoleon.
Other mistake: Dr Anne wets her dress by dropping water on it, but her dress is dry afterwards. (00:54:00 - 00:55:30)
Other mistake: When Stallone stops the bad guys in the semi full of cocaine, they fly through a windshield that is apparently made of plate glass, and not the safety glass found on almost every other vehicle windshield on earth.
Other mistake: During the one game playoff against the Yankees, the runner Taylor picks off at first base has the same number as the batter who had just struck out. Also, the number they both wear has been long since retired by the Yankees and therefore no player could ever wear it again. Again, in the first game against the Yankees, the first base coach also has the same number, making it three Yankee players with the number 37.
Other mistake: When James is taking Mollie to the hospital, he drives through a construction site and starts driving backwards, then does a 360 degree turn. In the aerial shot, you can see the skid marks from previous takes.
Other mistake: When Tom Hanks is walking down the stairs a chainsaw comes through the wall. If you look at the wall a second earlier you can see a line where the chainsaw is supposed to come through.
Other mistake: In the bar scene where Dooly is being beat up by the bar thugs, When Jerry Lee starts to attack them there is a shot of the dog lunging at the thugs. If you look carefully at the shot the dog is fake. You must look very carefully it is only a second. (00:32:30)
Other mistake: When Doc, Marty and Jennifer have arrived in 2015 Doc tells them that the time of the day is 4:29pm. However the destination time is still shown on the time circuits' display from their time travel to the future - the two times should match, but the destination time has the bottom AM/PM light illuminated, while the current time has the top one lit. They didn't arrive or leave at 4:29am, so something's wrong somewhere. (00:04:42)
Other mistake: Another note about Clark's falling through the ceiling and onto his son's bed: Take note of the shot of him in the attic after falling through the ceiling. He's standing on the upper bunk of the bed now, but from the shot in the attic, he's only down to his knees or so. Assuming his home's ceiling joists are 8 inches or so, then the mattress of the upper bunk would have to be no more than, say, 10 inches from the ceiling for that much of him to still be in the attic while standing on the bed. I've never seen a bunk bed whose upper bed gave you less than a foot of space between mattress and ceiling! (00:33:05)
Suggested correction: The bunk bed is not normally used by two people - there is a scene in the kitchen where Audrey talks about having to share with her brother. It is possible that this bunk bed used to be in a different location, but has been shifted to this lower ceiling at some point in the past.
Other mistake: Eddie describes her brain tumor as inoperable because her brain wraps itself around it like jellyfish. The German subtitles translate 'jellyfish' into 'eel in jelly'. (00:37:20)
Other mistake: In the alley scene immediately following the jail escape Dave and Wally are trying to open a door, Dave steps away from Wally and while looking away says "There's an alley!" Wally hollers out "Dave!" and Dave whips back around and says "I'm right here, I'm right here!" He wouldn't have been able to have heard his name being shouted since he is deaf. (00:39:00)
Other mistake: Watch closely as Investigator Natsuo kicks through the windshield and kicks the villain in the face. The villain's head caves in like it is made of cardboard.
Other mistake: When Ana's fiance lands to pick them up, the Cessna that he flew could only fit five people and that would be three people pushed together in the back. Also that particular plane can't take off in that short of a distance.
Other mistake: In the scene where Miss Daisy asks Hoke if he has had the air conditioning checked, the car they are in doesn't have air conditioning, as there are no clear tubes that transition the airflow from the rear package shelf to the ceiling vents that aren't there.
Other mistake: In the opening scene in the office, when Andrew McCarthy says, "Let's go to the beach" and runs off, you can see that the other guy's PC, which he has been working on, has no power cable plugged in.
Other mistake: When the girls tell Harley that Carson has taken a bus back to Spartenburg, he says that is the middle of the night, however it is daylight outside.
Other mistake: When the mastermind is first shown behind his screen, he inflicts spittle onto one of his gang members by saying "plan is preceding perfectly." However, the mastermind is talking from behind a screen, and thus it would be impossible to get them.
Other mistake: When Harry is being spun round on the ceiling fan you can see that they aren't moving fast enough to hold his body in a stretched out position,especially considering his bulk.
Other mistake: In the Italian dub, the kids at the birthday party vociferously ask for their hero; Tree Man instead of the original He-Man. He-Man was very popular in Italy too at the time, it was not an obscure reference that needed any adaptation - not that there is or was any character named Tree or Tri Man in Italian pop culture.
Other mistake: When Amy hits the button to tell her dad that breakfast is ready, he tries to type "I'll be down in five minutes." However, the message on the strip of paper says "I'll be down in five mimmicks." Amy says, "Typing with his gloves on again." Even if someone was typing with their gloves on, the blatant misspelling would not happen.
