Corrected entry: The villain's Bentley is parked at the bottom of the steps from the Albert Hall, in front of a white Ford convertible - a Zephyr or Zodiac, quite a rare car even in those days. After Harry Palmer has a fight with the villain's sidekick, the Bentley speeds away, and we see the Ford still parked by the curb. Except now, it's dark blue.
The Ipcress File (1965)
1 corrected entry
Directed by: Sidney J. Furie
Starring: Michael Caine, Nigel Green, Guy Doleman, Sue Lloyd
Genres: Thriller
Other mistake: In the Dr Radcliffe lecture scene, Harry removes his glasses to clean them revealing his poor eyesight. But in the final escape scenes when he determines and shoots the traitor, he is not wearing glasses.
Palmer: The fellow whose job I'm taking, will he show me the ropes?
Major Dalby: Maybe - if you're in touch with the spirit world.
Palmer: I beg your pardon?
Major Dalby: He was shot this morning.
Trivia: Many years after the film's release, Michael Caine revealed that the studio wanted to cut the scene of Palmer cooking as they feared it would make audiences think that Palmer was gay.
Correction: Do you think they spraypainted the car while they shot the fight scene? There is easily enough time for the hite car to leave and the blue car to arrive during the very long fight scene.
