The Ipcress File (1965)

Continuity mistake: Harry Palmer uses the leather wrist restraints to lacerate his wrists - the pain enables him to resist being involuntarily hypnotised. The next time he is woken roughly by the guards for another hypnosis session, his wrists are unmarked.

Other mistake: When Palmer raids the factory in search of Radcliffe, he summons a Land Rover to break down the warehouse door with a silent wave of his hand, but the Land Rover appears from behind a corner and therefore could not have seen him.

Continuity mistake: When Palmer comes home and finds the dead American agent on the floor in his flat, the dead agent's eyes and mouth are both wide open. There is a cut to Palmer standing in a door-way, then a cut back to the dead agent, whose eyes are now half-closed and his mouth completely closed.

Trivia: Len Deighton, the author of the original novel, also published a series of cookery books and wrote and drew a weekly strip cartoon-style illustrated cooking guide in London's The Observer newspaper - titled 'Len Deighton's Cookstrip'. In the first kitchen scene, where Harry Palmer is making coffee, you can see one of these strips is pinned to the wooden post next to the table.

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.
