Two of the most popular stars, James Garner and Clint Walker, quit over their conditions. Garner never returned to the Warner's fold during this period, instead moving forward into a major theatrical film career. Successful Warner's television stars found themselves in leading roles of many of the studio's theatrical films with no increase in salary. Efrem Zimbalist Jr. was simultaneously the lead of "77 Sunset Strip" briefly overlapping with a recurring role as "Dandy Jim Buckley" on "Maverick", and also headlined several films until exhaustion forced the studio to give him a rest. Many other actors under contract to Warner's at the time, who despite their work conditions, did see their stars rise over time, albeit for most only briefly, included Jack Kelly, Will Hutchins, Peter Brown, Ty Hardin, Wayde Preston, John Russell, Donald May, Rex Reason, Richard Long, Van Williams, Roger Smith, Mike Road, Anthony Eisley, Robert Conrad, Robert McQueeney, Dorothy Provine, Diane McBain and Connie Stevens. Edd Byrnes and Troy Donahue would become teen heartthrobs. Another contract player, Englishman Roger Moore ("Maverick" and "The Alaskans"), was growing displeased with Warner as his contract was expiring and would relocate to Europe from Hollywood, becoming an international star on television, and eventually, in theatrical films, playing James Bond among other roles. Warners also contracted established stars such as Ray Danton, Peter Breck, Jeanne Cooper and Grant Williams. These stars often appeared as guest stars, sometimes reprising their series role in another TV series.
