Factual error: While Bridger is watching the film of the Mafia boss following Beckerman he signals for the film to be stopped so he can look at the close up shot of the man. He is watching a 16mm film shown through a bog standard projector - stop a film like that for more than two seconds without closing down the projector shutter (this doesn't happen - if it did the screen would darken instantly) and it will melt and catch fire. This doesn't happen.
Plot hole: Why on earth do they drive the Minis up the ramps into the bus while it is moving? They are on a long, straight, relatively quiet stretch of road, but there are cars and buildings about. That ramp is going to make a noise like the sky coming down (we see sparks as it scrapes on the road) and they put on a display anyone would be, frankly, amazed to see. Don't they think one single person would call the police? Don't they think that reports of three brightly coloured Minis will be connected with the recent robbery? They cannot possibly think they have to load the Minis on the run in order to elude the police; they have lost the police cars and are no longer being pursued. Why not just park the bus on the hard shoulder and drive the Minis sedately up that ramp? An unusual sight, maybe, but nowhere near as clumsy, obvious and attention-getting as the way they do it. They are asking to be pulled over and arrested.
Trivia: The film is primarily about cars and driving. Star Michael Caine could not drive at the time the movie was made. Charlie Croker is assumed to be driving when he picks up his Aston Martin at the garage but in the next shot, we see it arrive outside a hotel. Caine only gets out of the stationary Aston Martin. In other scenes, including the trip to Turin and the gold heist, Caine is a passenger. However, he is seen driving his E-type Jaguar into the Turin building where the Minis are being modified. The DVD confirms that Caine couldn't drive, but could just about manage the basics.
Charlie Croker: It's a very difficult job and the only way to get through it is we all work together as a team. And that means you do everything I say.
