John Travolta
John Joseph Travolta (born February 18, 1954) is an American actor, film producer, dancer, and singer. Travolta first became known in the 1970s, appearing on the television series "Welcome Back, Kotter" (1975–1979) and starring in the box office successes "Saturday Night Fever" (1977) and "Grease" (1978). His acting career declined through the 1980s, but enjoyed a resurgence in the 1990s with his role in "Pulp Fiction" (1994), and he has since starred in films such as "Get Shorty", "Broken Arrow", "Face/Off", "Swordfish", "Be Cool", "Wild Hogs", "Hairspray", and "The Taking of Pelham 123".
John Cazale
"The Godfather" was Cazale's feature film debut. The film's star was one of Cazale's idols, Marlon Brando. The film broke box office records and made Cazale and several other previously unknown co-stars famous. Coppola, impressed with Cazale's abilities in the small role, wrote the part of Stan for him in his next film, "The Conversation" (1974), in which he co-starred with Gene Hackman. He reprised his role as Fredo Corleone, now significantly expanded, in 1974 in "The Godfather Part II". Bruce Fretts, in "Entertainment Weekly", wrote that "Cazale's devastatingly raw turn intensifies the impact of the drama's emotional climax". Co-star Dominic Chianese said: "John could open up his heart, so it could be hurt. That's a talent few actors have."
