Marianne, Easy A
Snow White goes Greek in this modern day interpretation of the fairytale classic, where Amanda moves into a house with seven dorks—see what they did there?—after finding out that the sorority life isn't for her.
Sydney White, Sydney White
Amanda totally nailed the role of a holier-than-thou mean girl.
Host, The Amanda Show
The actress picked up an impressive three Favorite TV Actress wins at the Kids' Choice Awards for her role in the sketch series.
Kaylee, Big Fat Liar
Amanda made her big film debut in this film and she certainly didn't disappoint—the film brought in a whopping $48 million. Those numbers don't, ahem, lie!
Holly, What I Like About You
Aww, remember when Amanda played Jennie Garth's fresh-faced and cheeky younger sister in this television series?
Viola, She's the Man
The young star was nearly unrecognizable when she played a teen boy in this take on Shakespeare's Twelfth Night. We're sure even the Bard would've appreciated her entertaining performance.
Penny Pingleton, Hairspray
The multitalented gal proved she could sing just as well as she could act in this remake of the '80s classic.
Daphne Reynolds, What a Girl Wants
While what a gal does actually want may be up for debate, we're sure we want to see more of Amanda taking on comedic roles like this one. Plus, the fact that Brit hottie Colin Firth played her dad didn't hurt either.
