Outstanding Performance by a Female Actor in a Leading Role

This is the first time Jessica Chastain and Jennifer Lawrence have gone head-to-head against one another, given that for previous award shows, they've been separated by category: comedy vs. drama. With that, here are the SAG nominees for Best Female Actor in a Leading Role:

Jessica Chastain, Zero Dark Thirty
Marion Cotillard, Rust and Bone
Jennifer Lawrence, Silver Linings Playbook
Helen Mirren, Hitchcock
Naomi Watts, The Impossible

At 22 years of age, she's the category's youngest ever winner, but that doesn't faze Jennifer Lawrence who makes her way to the stage to collect the Actor. The only thing more unbelievable than this win is the Dior couture mishap as she tears her dress while walking up the stage steps. Oh, and something else equally unbelievable? She scored her SAG card after appearing in a promo for MTV's My Super Sweet 16. What no Law & Order guest role?!
