Actress Lucy Liu was forced to bare all in new vampire movie RISE when she got confused by a clause in her contract.

The KILL BILL star was only alerted to the 'European nudity' condition a day before signing up for the role as reporter SADIE BLAKE in the horror film - but didn't understand what the term meant.

She says, "I was like, 'What is this? I'm not going to sign this! What's European nudity?'

"But what it meant, basically, is that Europeans are open and free and so much more relaxed about nudity.

It meant there's frontal nudity."
