John Travolta may be a thoroughly established actor, but he still has to fight for his roles. He and Rob Lowe chatted about that and more, including staying relevant in Hollywood and Travolta’s preparation for “The People v. O.J. Simpson: American Crime Story,” for Variety and PBS’ “Actors on Actors.”

The entire interview can be watched when the two-part fourth-season premiere of “Variety Studio: Actors on Actors” airs June 12 and June 19 on PBS SoCal. Presented by Shopbop/East Dane, the episodes will also be available to stream on Variety.com.
