From the interview, on what inspired Licorice Pizza:
A very long time ago I was walking around my neighborhood, and I passed Portola Middle School. It was picture day, and I saw this very energetic teenager flirting with the girl who was taking pictures. It was an instantly good premise. What happens if you have a kid invite an older woman to dinner, and what if that girl against her better judgment says yes? That seemed ripe for humor. That didn’t go anywhere, but then I had a friend who grew up in the San Fernando Valley. He was a child actor who got involved in the waterbed business. And he told me all these stories, and each one was more wonderful than the last. Like there was this time he’d appeared in the movie “Yours, Mine and Ours” with Lucille Ball, and he was on his way to New York for a publicity tour and needed a chaperone. He ended up hiring a burlesque dancer who lived in his neighborhood to take him. And Lucille Ball was on her second marriage to Gary Morton, and she used to scream “Gary!” all the time. That was my friend’s name, so he’d think, ‘Holy shit, she’s yelling at me.” But she was screaming at her husband.
