John Travolta is perhaps best-known for his disco-dancing days during "Saturday Night Fever" or his suave performance in "Grease," but he left musicals for the big screen. Travolta earned an Oscar nomination for his portrayal of Vincent Vega in "Pulp Fiction," a film that many considered to be his big comeback.
With the help of a fatsuit and wig, Travolta sang again (after 30 years) as Edna in the movie "Hairspray," based on the 2002 Broadway production. (AP Photo)
