Get to Know the Cast of Divergent Before It Hits Theaters March 21

In between her five-year tenure on ABC Family's The Secret Life of the American Teenager, Woodley starred in several films, including 2011's The Descendants (opposite George Clooney!) and 2013's indie hit, The Spectacular Now. Want to see how much she's changed? Check out her transformation.

Teller breaks out of his good guy niche playing the evil Peter in Divergent. Previously, he's played lovable, boyish characters in films like That Awkward Moment, The Spectacular Now, and the 2011 remake of Footloose.

Goldwyn, also known as Mr. President on ABC's hit drama Scandal, puts politics on the back burner to play Tris's father, Andrew Prior.

For four years, you could see Maggie Q busting bad guys on the hit CW series, Nikita, and now she's back-this time on the big screen as Tori, a Dauntless tattoo artist who helps guide Tris.

Another one to watch, Lamb's made a name for himself starring in Starz's The White Queen, but his role as Edward, a fellow Dauntless transfer, will be his first major role on the big screen.

The British actor is known for his turns in films like Great Expectations and Tormented, but you may also recognize him from Harry Potter and the Goblet of Fire--he played Ravenclaw Quidditch captain Roger Davies.

The son of actor and director Michael Madsen is beginning to gain momentum in the industry. He is appearing in a variety projects, but his role as Al, one of the Dauntless transfers who develops a crush on Tris, is his biggest role yet.

After over 20 years in the business, Phifer helps bring some star power to the cast playing one of Dauntless's ruthless leaders, Max.

The veteran actress and two-time Golden Globe nominee has had a long list of standout roles, and from the looks of her packed 2014 schedule--she's set to star in 5 projects this year!--it doesn't seem like she'll be slowing down anytime soon. See how she's grown up in the spotlight.
