Revealing mistake: During the fight scene in the belly dancer's room, Bond spins the bald guy around to avoid being hit by a chair. When the bald guy gets hit in the back with the chair, you can see a large rectangle of padding under his jacket.
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)
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.
Factual error: The scene in which the Beechcraft Baron hits the Boeing 747 in flight plumbs new depths in cinematic absurdity. Assuming both aircraft are at their normal cruising speeds - they appear to be - and the Beechcraft has half a fuel load left, it will hit with the same energy as 7,700 kgs of TNT. The Beechcraft Baron weighed 3,200 kg and the two aircraft would have a closing speed of something like 700 kmh. Even a glancing blow would tear the entire front half of the 747 to bits - there would be virtually nothing of the fuselage left intact all the way back to the wings, and the film shows the two aircraft on course for a head on collision.
Continuity mistake: This film's set in the 50s, but the actors use 20 Austrian Schilling bank notes, which were only issued in the mid 1970s.
Continuity mistake: When the crook kicks the door on a building in the fake town it falls over, but the same building falls over again when the dynamite goes off. (01:21:25)
Factual error: One of the main characters has a Harley Davidson. The movie is supposed to take place in the fifties. The Harley had an electric start primary cover which wasn't made by Harley until 1965.
Factual error: While the band's clothes and hairstyles are right for the era the film was set in (the sixties), the hair fashions and clothes of the extras, especially the audience and security men, are from when this film was made - the mid seventies. The crowd scenes were taken at contemporary David Essex concerts which explains the 70's fashions seen.
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)
Factual error: In the Bosphorus scenes, as the ferry crosses from the Asian to the European side of Istanbul, in the distance large trucks can be seen speeding along the coastal road opposite. Well before their time.
Continuity mistake: When the girl is driving the truck, you can plainly see the front bumper get bent, but a few scenes later it is straight again.
