The Grease star earned an Emmy nomination for his portrayal of top defence attorney Robert Shapiro in the TV adaptation of American footballer-turned-actor O.J. Simpson's 1995 murder trial, but Travolta admits it took him four months to decide whether or not to take on the job.

Naming the pals who encouraged him to take on the role, he tells GQ magazine, "It was Spielberg. It was Oprah. It was Rita (Wilson) Hanks and Tom Hanks. And it was (former Disney magnate) Michael Eisner."

"They all thought it was completely the right move," he continued, revealing Spielberg and Eisner were "the most enthusiastic".

The series helped to boost Travolta's Hollywood profile once more, and he admits being recognised for his TV work has given him a new sense of pride.

"You have these points in your career when you are associated with high quality, with depth, communication, and things that matter on a social level," he explained. "And when you hit those notes - whether it be Primary Colors, or on the cover of Time magazine, or Pulp Fiction, or Saturday Night Fever, or Urban Cowboy - where you're affecting the society on a global level, then you feel a different kind of pride. It's beyond the pride of success. It's the pride of... integrity, I guess? You're not always guaranteed to be involved with projects that will hit those notes. When you are, you really do register it."

The People v. O.J. Simpson: American Crime Story was nominated for a total of 22 Emmys, taking home nine, including top awards for Sarah Paulson, Courtney B. Vance, and Sterling K. Brown. The show, on which Travolta also served as an executive producer, was also named Outstanding Limited Series.
