John Travolta still under pressure

John Travolta says he doesn't feel any less pressure to deliver a good performance now he's approaching his 60s.

The Hollywood star, 58, is back on screen in his first film since his16-year-old son Jett died three years ago after suffering a seizure on a family holiday in the Bahamas, and more than three decades since finding fame in Saturday Night Fever.

John stars as a Drug Enforcement Administration agent in Savages, a thriller directed by three-time Oscar-winning filmmaker Oliver Stone.

But he said: "The necessity to do well is high at this level. When the industry knows there's a great script and there's a big studio supporting it and the actors are all worth their keep, there is a pressure.

"You want to live up to a standard."

He said of working on the film, which also stars Taylor Kitsch, Aaron Taylor-Johnson and Blake Lively: "The great thing is, Oliver knows you'll deliver and expects you to deliver and if you don't, he'll challenge you on it but that's OK because you want to do your best."
