The Devil Wears Prada star Emily Blunt fears she let director Mike Nichols down while filming love scenes with Tom Hanks in new film Charlie Wilson's War - because she was awestruck by the Oscar winner.

Blunt couldn't believe her luck when she was cast opposite Hanks and Julia Roberts in her moviemaking hero's latest film - but she isn't proud of her acting.

She says, "I have a rather raunchy scene with Tom Hanks, and he couldn't have been nicer about it.

"It was that weird thing where I'm crawling all over him, and suddenly my mind drifts off and I'm like, 'Oh, I loved you in Turner & Hooch.'

"The whole time I was completely starstruck by Julia and Tom. I would love to work with Mike Nichols again and not be overwhelmed by the people around me."
