The pair first met when Keaton was cast opposite Allen in his 1969 play Play it Again, Sam. He described them both as being shy, though they achieved a breakthrough during a lunch pause at rehearsals.
“That was our first moment of personal contact,” Allen penned. “The upshot is that she was so charming, so beautiful, so magical, that I questioned my sanity. I thought: Could I be in love so quickly?”
“I never read a single review of my work and cared only what Keaton had to say about it,” Allen went on. “If she liked it, I counted the film as an artistic success. If she was less than enthusiastic, I tried to use her criticism to reedit and come away with something she felt better about.”
