For the four months of filming, she and Albert Finney pursued a frolicsome romance in the most discreet manner possible. They rehearsed in private, they went to beaches with no other company, they dined à deux. Her marriage, she had to accept, was merily legal, and Finney was divorced. More to the point, he had a keen sense of humor, he was highly intelligent, he took his craft with utmost gravity, and he had a personality that was enormously beneficial to Audrey at this point: he was entertaining and exuberant. The relationship was refreshingly uncomplicated and so perhaps unique in her romantic life.
“I didn’t even know the Audrey of the last few weeks on this film,” recalled Donen. “She overwhelmed me. She was so free, so happy. I never saw her like that - so young! I don’t think I was responsable. I guess it was Albie.”
“She and Albie had this wonderful thing together,” recalled writer Irwin Shaw, a frequent visitor to the production that summer, “like a pair of kids with a perfect understanding and a shorthand of jokes and references that closed out everyone else. When Mel was there, it was funny: Audrey and Albie got rather formal and a little awkward, as if now they had to behave like grown-ups”.
As for Finney, he was discreet then and later: his relationship with Audrey, he said, was “one of the closest I’ve ever had”. Audrey was typically equivocal. “I really love Albie”, she said with a smile, and that was that.
