Both the movie and its lead dude Cooper Hoffman move fast. He gets Alana Haim to be his chaperone on a promotional trip for his acting career, then things escalate, until he’s arrested for murder while selling waterbeds at a teenage fair, and flooding the house of Barbra Streisand’s boyfriend. She directs the ads for aspiring politician Benny Safdie, he opens a successful pinball palace. Haim gets to run a lot. The final scene, I dunno, but hey, why not.
