How's this for irony? When Angelina Jolie — who plays video-game vixen Lara Croft in Tomb Raider (opening Friday) — was asked by one of hubby Billy Bob Thornton's kids for Tomb tips, the stepmom was stumped. "Every time he got stuck [with the game], he would look at me for help," she laughs. "I could not help him at all. I can't play it. I get frustrated with that game."

Fortunately, Jolie's father, Jon Voight — who also plays Lara's papa, Lord Croft — does a better job putting her at ease in unfamiliar situations. "It's a very unique experience to get to work with your parent," she says. "I think we were probably both nervous for each other... because it meant so much to us. But when he showed up, I was a little more calm. I would be getting dressed up and trying to look tough, and Dad had this really silly pig toy that he would wind up and send it walking in my room."

Gesturing at her chest, Jolie wryly mentions that "dressing up" as Lara meant packing a padded bra in her gear. "I am a 36C," she shares. "In the film, I am a 36D. In the game, she's something like a 40 double-D. That was a little too cartoonish. So, I had a bit of a padded bra, but it wasn't so far off — I was woman enough to handle the role."

Having carried that extra cushioning up front (and not quite enough in other places) during the shoot, the actress says her kick-ass action sequences took their toll. "I definitely have some scars from this film," she says. "Also, the braid kept hitting me in the face! But I was surprised that I had better physical ability than I had thought.

"When I was in training," Jolie continues, "there was one night I was sitting in the bathtub with all my bruises and a little cut knee crying, 'What am I doing? I'm not going to be able to pull this off.' But it's a great feeling to be physical. It helps with my fearlessness — and I've always been ridiculously fearless."
