Acting with Ben Kingsley had Mary-Kate Olsen more nervous than kissing him!

London, July 16 (ANI): American actress Mary-Kate Olsen revealed that having to do a kissing scene with British actor Sir Ben Kingsley was a piece of cake compared to acting with him.

The part in which she has to do the scene with the 64-year-old actor is in her latest movie 'The Wackness'.

Olsen, 22, revealed that she was so worried about acting opposite to her idol that she never gave kissing Kingsley, who is old enough to be her grandfather, a thought.

"It is all part of being an actress," the Sun quoted her as saying.

"But I was so in awe of Sir Ben I was more nervous about acting alongside him than I was about the kiss," she said.

Kingsley has on the other hand praised the young actress on her acting, stating she's an expert at her job.

"Mary-Kate's portrayal of this girl is perfect - she's hysterical. She's a pro. It makes sense. She's been in this business a lot longer than I have," he said. (ANI)
