Paul Thomas Anderson’s Licorice Pizza (2021) may be a fictional coming-of-age story, but the nostalgic Hollywood film features many characters portraying or based on real-life people. Licorice Pizza documents the misadventures, tumultuous friendship, and romance of Alana Kane (Alana Haim), a photographer’s assistant in her mid-20s, and Gary Valentine (Cooper Hoffman), a 15-year-old actor and entrepreneur. Set in the early 1970s, Licorice Pizza also includes real Hollywood-set memories of Anderson and his friend Gary Goetzman.
