Marlon Brando once approached director Michael Winner on the set and requested that the script be rewritten, to which Winner responded: "Marlon, you've had the script for nine months, we haven't got time to redo the whole bloody thing now, thank you very much. It's a low budget film and you had a great deal of time to make this speech. It's no good making it standing in a country lane in Cambridgeshire with Francis Ford Coppola behind the barrier with the crowd watching. This is not the time dear - I'm terribly sorry".
Winner made a bet with Brando while the actor was in London filming Superman (1978) over the pronunciation of the word "integral," with the wager being that the loser "has to sell French ticklers, that is a male condom with bubbles on it, in Piccadilly for an hour." Winner lost the bet, and he discovered when Brando died in 2004 that he had kept the photos of Winner selling the condoms in Piccadilly Circus.
Winner recalls Brando becoming upset that the BBC was covering the Olympics and referring to male Chinese athletes as "Chinamen," but when he would call to complain they would hang up thinking it was a prank call. He enlisted Winner's help in getting through to them, and the next day the coverage started referring to them as Chinese athletes.
They went to a pub in search of an Irishman to help teach Brando the accent, "and he said to me 'is that an Irishman over there?' and I said 'no Marlon that's a Pakistani.'"
