In 1975, John Travolta landed a star-making role on this classic TV sitcom. As Vinnie Barbarino, the cocky leader of a group of teenage misfits, John sent teen girls' hearts aflutter.

During his stint as a James Buchanan High School "Sweathog," John earned his heartthrob status, which led to a string of film roles.
