Continuity mistake: When Dr. Frankenstein introduces himself to the monster with a soothing "Hello, there", his right hand is on the restraint over the monster's chest. The next shot shows the doctor placing his hand on the restraint again.
Visible crew/equipment: When the Hitchhiker was thrown out of the van and chases after them the camera cuts to the inside of the van and a crew member wearing a red T-shirt and clapper board are visible reflected in the window from the inside view.
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.
Revealing mistake: In scene at the brothel, with the senator and the dead prostitute, the supposedly dead body is breathing in the last shot of her, just after Tom Hagen says "it'll be as if she never existed". (01:15:30)
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)
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: When Mongo enters Rock Ridge on the steer, the cuff on the chain around his neck instantly switches from open end facing left to facing right in the next cut.
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.
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: In the scene where Thunderbolt and Lightfoot are in the car with the crazy driver. The car goes over the embankment and as it flips you can see a wheel break off. A short time later they both drive off in the same car, with the wheel attached again.
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 Barbara Windsor is getting undressed to prove that she is not a man, there is a red garment which is crumpled up on the bed behind her. When she finishes undressing the red garment is spread fully across the bed.
Continuity mistake: During the chase where Larry's Charger knocks a police car in the river, the '69 Charger becomes a '68 Charger in one shot, as seen from the front. The '68 has a different grille than the '69 models. (01:09:40)
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.
Revealing mistake: When Crewe dumps the car in the river, you can see the wire attached to it that was used to pull it out of the water. Burt Reynolds mentions it on the DVD commentary.
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.
Revealing mistake: When Mr. Green pulls out of 28th Street, we see him disengage the "Dead Man's Feature" (by pressing down on the throttle with his hand). However, he does not actually move the control lever to make the train move. In that position, the train is at "idle" and will not accelerate.
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.
Suggested correction: What matters is how much of the small plane's kinetic energy was deposited in the 747's structure. A glancing blow would deliver less energy than a head-on collision, because it lessens the total time interval of the impact. Another important thing is if the small plane shattered or stayed largely in one piece during the collision. If it promptly shredded on impact, then each little fragment carried away its portion of the total energy. Smaller pieces of something as light as that plane would immediately get caught in the powerful airflow and be diverted around the 747.
Absolute rubbish. Airliners do not survive mid air collisions.
