In her new movie, Salt, she plays a character that was originally going to be played by Tom Cruise. Some changes to the script did need to be made: "For example, the male character had a child, and he knows he’ll be in danger much of the time. And we realized that, as a woman, if you knew your life was at risk, you’d never have a child." And:
The slender Angelina also had to modify the character's demeanor to convincingly play a tough, gun-slinging spy. "The physicality had to change too," she says. "I’m smaller than everybody, so how do I go up against a bunch of men without looking silly? How do I fight?"The slender Angelina... she's a lot skinnier than she was when she played Lara Croft. Compare. I prefer the strong Lara Croft look, but I appreciate the attitude that Jolie seems to have even when she's too skinny.
She adds: "We made her meaner than a guy, and dirty. She uses the walls, the fact that she’s lighter and can throw herself around. It’s the Chihuahua up against the big dogs.”
