Factual errors: In the flashback scene of their father's suicide, the Colt .45 Commander used had its hammer closed after he shot himself. The hammer would have been in the fully cocked position after firing and can only be closed manually. (more)

Trivia:
Producer Robert Evans was set upon getting Laurence Olivier to play the part of Szell. However, because Olivier at the time was riddled with cancer, he was uninsurable so Paramount refused to use him. In desperation, Evans called his friends Merle Oberon and David Niven to arrange a meeting with the House of Lords (the upper body of the UK's parliament). There, he urged them to put pressure on Lloyds of London to insure Britain's greatest living actor. The ploy succeeded and a frail Olivier started working on the film. In the end, not only did he net an Oscar nomination for Best Supporting Actor, but his cancer also went into remission. Olivier lived on for another 13 years. (more)
