From Joseph Cotten's 1987 autobiography Vanity Will Get You Somewhere:
The following day Orson and I had a date for lunch with two gentlemen (not from Verona, I fear). They were two tough and exceedingly wealthy businessmen. The reason for our meeting was simple; Orson needed money for his next film and he intended to acquire some of theirs.
Late that afternoon, we spotted Churchill swimming in the Lido. In a flash, Orson had his swimming trunks on and was in the water beside him. He was talking, but thank heavens I couldn’t hear what he was saying. Apparently neither could Churchill, for he just turned and swam in the other direction.
Later I asked Orson, “What did you dare say to him this time?”
“I apologized for being fresh,” he said, “but I told him I just wanted to impress two gentlemen whose money I needed for a film.”
Rather unnecessarily I asked, “Did he reply?”
“No,” said Orson.
That evening, we walked into the dining room, our two prospective backers following gloomily. As we reached Churchill’s table, he stood up, looked directly at Orson, and bowed slowly and deeply.
We got the money.
