Revealing mistake: Watch carefully as the statue falls on the bartender. It barely touches his chest and rests on his left thigh. As the bartender slumps dead you can see a wide open gap between his whole upper body and the statue. Even if it crushed his thigh it would not have killed him so quickly. When the bartender slumps down the statue rocks freely as he brushes against it; obviously a styrofoam replica.BocaDavie
Factual error: Just before Walther Matthau meets Susan Sarandon for the first time in her dressing room in the movie theater, he passes a poster for "All Quiet On the Western Front" in the hall. "All Quiet On the Western Front" wasn't made until 1930 and this film is supposed to take place in 1928.
Continuity mistake: When Jingle, Jangle, and Mrs. Claus pay a visit to Mother Nature, Mother Nature calls her sons beside her - Snow Miser and Heat Miser. She then turns to Snow Miser and asks him to allow a little snow fall in the South, and then turns to his brother, Heat Miser, and asks to allow just "one Spring day at the North Pole." The words are correct dialog, but she should have said each of those lines to the OTHER brother. (00:39:40)
Continuity mistake: In the scene where Inga, Fredrick and Igor throw the net over the monster, Inga sticks the syringe of the sedative in the monster's back but does not push down on the top, yet the monster still falls over. A few seconds later when she collapses on the monster, you can see all of the fluid inside spray out. (01:12:05)
Factual error: In the scene right after pinback shoots the beach-ball alien, we see the Dark Star space craft cruising past a planet with a sun in the background. You can see a reflection on the planet which is coming from the space craft. I'm sorry, but usually ships in space are not large enough to reflect off a planet, especially to the degree this one does. (00:48:20)
Continuity mistake: When Poirot and Mr. Ratchett first meet in the restaurant car, Poirot has to correct Ratchett's pronunciation of his name. Poirot then points with his right hand toward Ratchett, but when it cuts to a close-up of Poirot, both his hands are on the table. The angle changes back, and Poirot's hand is once again lifted.Twotall
Continuity mistake: When Hadrian jumps the mustang over the upturned car, the film slows down to show the jump in slow motion. When the car lands, it hits so hard the car spins around and ends up facing the cars it jumped. The scene is then repeated at normal speed, but just as the car would be shown spinning out, a shot of the car driving away from the accident is shown.
