TOKYO - Julia Roberts isn't planning a spiritual journey of her own after making the film based on the hit travel memoir "Eat Pray Love."

Roberts, a happily married mother of three, said she read and enjoyed Elizabeth Gilbert's best-seller long before the proposed movie script came across her desk and she jumped at the role. But she added she isn't looking to make any big alterations in her own life.

"No, no changes," Roberts said Wednesday in Tokyo, where she is promoting the movie's release. "I'm good."

Roberts, who was raised a Catholic but is a practicing Hindu, said the film offered her a chance to draw from her own experiences, but she said she did not convert because of the role.

Beyond that, she said she would keep her beliefs to herself.

"I've realized something my mother told me 22 years ago," she said. "You're an actor, act. Don't talk about politics or religion."

One departure for Roberts, 42, does lie ahead.

Roberts has done little TV work, but she is a producer of a documentary series, "Extraordinary Moms," airing in January on Oprah Winfrey's new cable network.

Roberts' next big-screen project is "Larry Crowne," which is set for release next year and reunites her with Tom Hanks.

On her work and longevity as one of Hollywood's most sought-after stars, she said her inspiration has never waned.

"Loving what you do is the secret to everything," she said. "I really do love the creative part of making movies."
