During the course of an ordinary week in Hollywood, movie producer Ben must navigate his way through shark-infested waters as he struggles to complete his latest projects. A demanding studio boss demands extensive changes to a movie starring Sean Penn, while another chief won't greenlight a project unless star Bruce Willis shaves his beard. Meanwhile, Ben tries to reconcile with his wife and maintain a relationship with his young daughter.
Unfortunately the movie What Just Happened is not yet available on Disney Plus.
