Julia Roberts hopes new film will be inspirational

Looking elegant in a white Stella McCartney tuxedo suit, the Pretty Woman star, 42, said she wanted people to be moved by the romantic drama, which is based on the best-selling memoir by Elizabeth Gilbert.

"I hope this movie inspires people to take a little bit more time out for themselves, and to appreciate what they have," she said on the brightly coloured carpet, which was decorated with floral arches.

The mother-of-three did not disappoint the hundreds of fans who turned out to support the Oscar-winning actress in the capital's West End, signing autographs and posing for photographs.

Eat Pray Love, which also stars Javier Bardem, James Franco and Richard Jenkins, follows a newly-divorced author as she quits her job to embark on a quest of self-discovery – feasting in Italy, finding the power of prayer in India and rediscovering inner peace and love in Bali.

"It has been a great challenge. It's a great book, a brilliant character and a wonderful cast," said Roberts.

"Filming in each country had its own challenges and appeal," she continued, adding that she admired Gilbert for being "so smart and funny".

Director Ryan Murphy described his leading lady as "stunning".
