Hollywood's Dynamic Duo

When a movie like this comes along, Tom says word spreads in Hollywood. "Movies like this, they exist as a possibility for the longest time," he says.

Julia didn't see the script until Mike Nichols, her friend and director in the film Closer, called one day. "When Mike called me and said, 'I have a movie that I'd like you to look at.' I just went ahead and said, 'I'll do it.' That's how much I love him," she says. "He said, 'No, no, you should look at it. Read it first.'"

While reading the script, Julia says she turned to her husband, Danny Moder, and said, "Oh, my God. I have to do this."

"It's just so great," she says. "Aaron Sorkin is really a masterful wordsmith, that one."
