Other mistake: When Ralphie and Flick are walking to school for the first time, they meet up with Schwartz, coming down the steps of his house which appears to be two houses down from Ralphie's. Later, when Ralphie is lying in bed after the soap in the mouth scene, the narrator (older Ralphie), states how "Three blocks away, Schwartz was getting his."
Other mistake: Towards the end of the movie, when Superman drops Gus off at the coal mine, Gus begins talking with the coal miners about him and Superman. He then rips open his shirt (as if he had a Superman costume on underneath). How did Gus know that Clark Kent tore his shirt like that in order to change into Superman, or keeps his suit under his clothes at all? The only people who know this fact are the ones who have seen the transformation from Clark to Superman, i.e. the audience.
Other mistake: During the scene when Clark is driving his family through the "rough part" of town in St. Louis, Clark asks his children if they are noticing all of the plight. Clark then makes the comment, "This will just make us appreciate what we have." A gunshot and a scream is heard, and Clark exclaims, "Roll 'em up!" A window is visible on Ellen's side of the car as she is rolling her window, up . But, there is no window on Clark's side of the car. Clark goes through the motions of rolling up his window, but . In actuality, he is rolling up nothing. Chevy Chase mentioned this during the cast commentary for the film. (00:13:50)
Other mistake: At the start of the movie it shows the house at front view and the sky is very very grey, it looks like it's about to rain, then after a short scene inside the house it goes back outside and the sky is clearly blue with not a cloud in sight. (00:12:00)
Other mistake: During the scene in which Jackie and his girlfriend are being chased on bikes they hide in a shop. When the men chasing them stop outside of the shop, the subtitles read 'This is a dead end, we'll spilt up'. Spilt up?
Other mistake: In the marching up and down the square skit, the guy behind Eric Idle is trying not to laugh. (00:33:35 - 00:34:05)
Other mistake: When Kenny throws the car in gear at the grocery store, he throws it into drive, but the car goes backwards.
Other mistake: As Buford takes off from the tow truck, a brown piece of metal is seen where there shouldn't be one. Probably for a later stunt.
Other mistake: When Fatima Blush intentionally water-skis straight up the ramp to the waterfront bar where James Bond catches her, she apologizes, "How reckless of me! I made you all wet!" To which Bond replies with his classic line, "Yes, but my martini's still dry." However, Bond's beige sport jacket (which should instantly show any water stains) is not in the least bit wet.
Other mistake: At the beginning of the film, the car with three wheels enters into the car park of the race track. You can see where the brake disc has gouged out the tarmac on an earlier take.
Other mistake: Mrs. Rutter has on full makeup when she wakes up in bed the morning of Dorfus' kidnapping.
