Gwyneth Paltrow's Proof Trauma  8/15/05

Gwyneth Paltrow is promising her performance in the big screen adaptation of "Proof" will be very different from her appearances in the stage original - because her dad died between the two.

Paltrow plays a daughter who comes to the aid of her dying math professor father in the film - so the death of her own father BRUCE in 2002 made the role an emotional experience.

She says, "The difference between my stage performance and my movie performance is that my father was still alive when I did the play.

"You don't what that's like until it happens. I had the first anniversary of his death while we were filming, so it was very, very raw for me."
