You haven't really made it until you've got a low-rent stripper masquerading as your ass double...

"...It's a messy movie, often intentionally, often not. And it shows off Keira as we've never seen her: raw, dirty, bad.

Fifteen minutes into the movie, she strips down to her underwear and administers a sweaty lap dance to a room full of Latino gang members, played convincingly by a roomful of actual Latino gang members. Other elements of the scene - Keira's ass for example - are less authentic.

'You have to decide for yourself what you're comfortable with', she says. 'I'm OK with topless, but I won't show my bottom. I used a double. Tony brought in three girls for me to chose from. Before they came into the office, I'm like, How do I act? I decided to be very businesslike. It was hard not to laugh, but I didn't want to offend anyone.

Anyway, they all had very nice bottoms, and I chose one. Then a few weeks ago, I hear about this girl in Vegas claiming to be Keira Knightly's body double. It wasn't her. She wasn't the girl in the movie.'

It's almost cliché by now: You haven't really made it until you've got a low-rent stripper masquerading as your ass double..."
