Corri was acquainted with many of the leading figures in the British theatre, including Joe Orton, and he recounts in his diaries how he asked her advice on how best to end his relationship with his lover, Kenneth Halliwell. She enjoyed a good relationship with Stanley Kubrick, who joked with her that in the home invasion sequence in "A Clockwork Orange" that she was cast in "the Debbie Reynolds part", a reference to Reynolds's role in the film "Singin' in the Rain" (1952). After completing "A Clockwork Orange", Corri kept in touch with Kubrick, who complained to her about the problem he had of losing socks whenever he did the washing, so for Christmas she gave him a pair of bright red socks, a humorous reference to her scene in "Orange", where after Alex had finished snipping off her red pyjama suit, she was naked except for a pair of red socks.
