John Travolta filmography
Travolta first became well known in the 1970s, after appearing on the television series Welcome Back, Kotter (1975–1979) and starring in the box office successes Saturday Night Fever and Grease. Although his acting career declined through the 1980s, Travolta also enjoyed a resurgence in the 1990s with his role in Quentin Tarantino's Pulp Fiction, and he has since starred in films such as Face/Off, Swordfish, Wild Hogs, and Hairspray.
John Howard (American actor)
According to David Shipman, "Howard..., was tried out in various capacities - supporting roles in A movies, and leads in Bs and on loan-outs. These last could be significant: the smaller studios had restricted contract lists and were prepared to pay well to borrow good- looking guys whose acting consisted mainly of not bumping into the furniture." 
Howard's first memorable role came on loan out to Columbia: as Ronald Colman's younger brother in "Lost Horizon" (1937), directed by Frank Capra. Capra had seen him in "Annapolis Farewell" and arranged for a screen test. The film was a huge success and really established Howard, who later said "without "Lost Horizon" I doubt very much whether I would have survived in Hollywood".
