Jimmy Hollywood (1994)

One thing stands between Jimmy and stardom. Reality.

Jimmy Alto is an actor wannabe who stumbles into the role of a lifetime. He becomes a vigilante crime-fighter, aided by his sidekick William, who has suffered a head wound and has problems with short-term memory. Jimmy's vigilante alter ego soon becomes a media wonder--but Jimmy remains a total unknown and his long-suffering girl friend Lorraine is getting fed up with the whole situation.
