During post-production, Michael Winner requested Oliver Reed's services to dub one particular scene due to bad sound recording on-location. When he phoned the Hampstead hotel where Reed was staying, the receptionist said that Reed had gone out the previous evening, gotten drunk, and been arrested outside a tube station. When he rang the Hampstead Police station, the desk Sergeant said Reed hadn't been charged because the officers found him so charming. A taxi pulled up outside Winner's house a few minutes later, and Reed clambered out. He was in no state to dub, and the session was useless. Winner recalled the next day, "He was very humble and ashamed that he'd spent the night in the cells. And then he went off, and that was the last time I ever saw him."
Oliver Reed promised Michael Winner that he wouldn't drink during the shoot. He was true to his word, but after production wrapped Reed called Winner drunk.
Michael Winner shouted "fucking morons" at his crew so often that they considered having t-shirts printed with "I'm a fucking moron".
