The trailer makes it look like a comedy, but wikipedia says it's a drama. Which seems more apt as Licorice Pizza was written and directed by Paul Thomas Anderson. Most famous for There Will Be Blood. Anderson also wrote and directed Boogie Nights, Magnolia, Punch-Drunk Love and Phantom Thread (for which he re-teamed with Daniel Day Lewis). I like that Anderson is going for a lighter tone with this movie. Could he stretch towards a romantic comedy at some point?
Cooper plays Jon Peters, who was Barbra Streisand's hairdresser, then boyfriend and then movie producer. I wonder if Anderson ever met him, or if this role is completely fictionalized. Lots of other talented people in the cast, Maya Rudolph, Ben Stiller, Sean Penn, Tom Waits and John C. Reilly.
