PENELOPE CRUZ - CRUZ PAIN MISTAKEN FOR ACTING

Actress PENELOPE CRUZ's screams of agony went unnoticed on the set of new movie SAHARA - because crew members were convinced she was merely acting.

The sexy Spaniard suffered a nasty cut to the wrist while hanging out of a moving train during the shoot for the film, in which she stars alongside boyfriend MATTHEW McCONAUGHEY.

However, her desperate calls for help were initially ignored.

She says, "I have a scar. I got cut right down to the bone. I was screaming and they thought I was acting - but I was in a lot of pain."
