He directed the It's Alive trilogy (mutant killer baby),Q: The Winged Serpent (low budget giant monster classic),The Stuff and wrote screenplays for William Lustig (Maniac Cop,Maniac Cop 2,Uncle Sam). The Ambulance stars Eric Roberts (The Expendables,The Immortals) as a Marvel Comics artist who falls for a beautiful woman who disappears after passing out on the street. it's a quirky take on the detective film where Roberts character attempts to discover what happened. James Earl Jones (voice of Darth Vader,Conan the Barbarian) has an entertaining roll as the detective Roberts deals with.
