The New York native appeared in other films directed by Mr de Palma, whom he met as a student, including Sisters, The Fury and The Black Dahlia.

He also played in horror movies including Eaten Alive and Night Terrors directed by Tobe Hooper.

Mr Finley is survived by his wife Susan and son Dashiell.
