Sienna Miller would tell a “total lie” if she said she didn’t care what people think of her work.

The 39-year-old actress insisted that she shouldn’t be “driven” by positive reviews and nominations, but she would be devastated if her performance in the new movie “Wander Darkly” were criticized.

She said, “It would be a total lie to say that I don’t want people to respond positively.

“I had to dig extremely deep so it would break my heart if everyone said, ‘She’s damned.’

“Any positive answer is very much appreciated. It just cannot be the driving force behind why you do something.”

In the film, Sienna plays a new mother Adrienne, who wakes up and stands over her own body after being pronounced dead and having to go back through her life to see where it all went wrong, and she admitted it didn’t Always easy to switch off at the end of a day of shooting.

She said, “This can be a painful experience. I never feel like I want to completely bury the person I play.

“But I’m pretty good at breaking up when I need to be around, like with my daughter or when I’m making dinner.

“You just have to be able to divide yourself.

“This is really specific to women; So much has been asked of me as a person other than my job, you know? Women are good at multitasking. “

Sienna is her biggest critic and she never watches her films again.

She told Grazia magazine, “I’ve never gone back and seen movies I’ve been in.

“I haven’t even seen all of them!

“There’s a director’s cut of ‘Factory Girl’ that seems to be a better version.

“When I was younger I had moments when some of the first films I made were shown and I looked at each other in total fear and wished I had worked harder.

“I was very, very critical.”
