Rob Lowe and John Travolta discussed the key to longevity in Hollywood during Variety and PBS’ “Actors on Actors” series.

“If you always try to give a quality of work that is viable; that minimum/maximum, it doesn’t work,” Travolta said about staying relevant in the biz. “Always strive for delivering your best and never do something for superficial reasons, then you’re going to survive for yourself and often for the audience.”

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.
