John Marley was an American actor and theatre director. He won the Volpi Cup for Best Actor at the 29th Venice International Film Festival for his performance in John Cassavetes' Faces (1968), and was nominated for an Academy Award and a Golden Globe Award for his role in Love Story (1970). He was also known to film audiences for his role as Jack Woltz—the defiant film mogul who awakens to find the severed head of his prized thoroughbred horse in his bed—in The Godfather (1972).

The Volpi Cup for Best Actor is the principal award given to actors at the Venice Film Festival and is named in honor of Count Giuseppe Volpi di Misurata, the founder of the Venice Film Festival. The name and number of prizes have been changed several times since their introduction, ranging from two to four awards per edition and sometimes acknowledging both leading and supporting performances.
