Other mistake: The reporting of the horse race used to sting Doyle Lonnegan stops as soon as the fake FBI agents raid the bookmakers. J J Singleton, who is reading the results of the race, stops when he sees the raid taking place. However, that was supposed to be a live broadcast from the racetrack itself. It should have continued. Lonnegan isn't stupid - he would pick up on something like that immediately.
Continuity mistake: When Falfa's Chevy flips over, we can see that it has no fuel tank at all in it. However, in the next shot the car now has a visible fuel tank, and it explodes.
Continuity mistake: At one point D'Artagnan reaches the Duke of Buckingham, who is on a hunt. He has just killed a stag and his hands are covered in blood. D'Artagnan rides up and offers him a note from Queen Anne. He wipes his palms with a cloth before he takes the note, but his hands are still covered with blood up to and above the wrists. When he reads the note, he and D'Artagnan take off on foot for his castle where they go into a private room behind the walls. Suddenly it is apparent that his hands are perfectly clean right down to his scrubbed fingernails and, without explanation, the plot-heavy sequence continues.
Continuity mistake: The hot knives that are set up in the King Lear scene towards the end of the film are sometimes smoking and sometimes not depending on the shot.
Continuity mistake: In the bedroom scene, Barbara Windor gets her dressing gown caught in the bed spring and has to take it off. When Sid James tries it on, he has no trouble removing it from the bed.
Audio problem: In the shop scene at Ginsberg and Cohen's, when Miles replies, "Something simple," he never opens his mouth to do so.
Continuity mistake: Trixie Delight's room number in the hotel is 235, but when Imogene and Addie go to Addie's hotel room, which is right next to Trixie's, the number on the door says 235, too.
Revealing mistake: At the beginning of the film, Stan reverses the bus into the manager's car. While the manager is under the bonnet looking at the engine, causing it to fall on him, you can see a rod with padding on it to stop the bonnet from hitting the manager. It is gone in the next scene.
Other mistake: Dunnaway fires a warning shot next to her father to encourage him to leave the property. In the sequence just before he leaves she fires one shot and there are two dirt eruptions near his legs.
Continuity mistake: As Charlie Brown, Patty, and Marcie are talking, the grandfather clock strikes four. Trouble is the pendulum is stuck in place, first on one side, then the other. It doesn't swing.
Continuity mistake: During the opening credits, the marching band pass the Queen Victoria statue in Windsor twice on their way to the castle.
Continuity mistake: Vicky is in her office, wearing glasses, until a girl knocks on her door and walks in, and the glasses have vanished.
Continuity mistake: When Linus and Lucy are talking to Snoopy he's got a shopping cart stuck on his right leg. Then, when he's getting on the bus it's suddenly on his left leg.
Revealing mistake: At the beginning of the movie, the coked-up sailor is shooting from a rooftop and screaming various racial slurs. Despite that, there's a big crowd building. When he shouts "Come and get me, honkies!" you can see people running way before he pulls out of the gun again and shoots. Not only that; some of the extras are just enjoying themselves and not keeping a straight face, far from being scared. (00:01:00)
Continuity mistake: When Jim comes to see Webster, Webster is in the bath with a sponge that he constantly wipes himself with, but the sponge moves from one hand to the other, repeatedly, without him actually doing it.
Continuity mistake: Victor Pivert is in full road rage mode as he is waiting at a road stop after skipping most of the line speeding through the emergency lane. As he bickers with his French compatriot, he hammers his horn initially with the right hand, then after a pause he starts hitting it with his left hand in a side view, which turns instantly into his right hand at the cut. (00:08:30)
Suggested correction: This isn't a mistake. The person "operating the radio" could easily have switched it off because of the commotion. Lonnegan would simply suppose this is what had happened. He is not going to instantly suspect someone is faking the whole thing.
