THR's Women in Entertainment 2012: Power 100

Colligan, 39, isn't afraid to try a novel approach: She turned the micro-budgeted Paranormal Activity into a multimillion-dollar franchise by hosting a wave of screenings of the first film in select cities before opening it nationwide. More recently, she came up with a savvy marketing campaign for Flight, which included a special prerelease screening and Q&A with Denzel Washington and Robert Zemeckis in New York that was streamed live into five theaters in Los Angeles and San Francisco. Up next are the Barbra Streisand-Seth Rogen comedy The Guilt Trip (Dec. 19) and Tom Cruise's Jack Reacher (Dec. 21). But Paramount needs a strong holiday season to improve its revenue standing. So far this year, its titles -- led by DreamWorks Animation's Madgascar 3 ($740.5 million) -- have taken in roughly $2.3 billion worldwide.

Moment I knew I wanted to work in the business: When, as an investment banker, I realized how jealous I was of people who worked in the business.

When I leave work each day, I can't wait to: Hang with my three boys, who are 7, 3 and 2.

Favorite way to unwind on the weekend: Make a great dinner and open a bottle of wine with my husband [producer Mark Roybal.

Most surprising song on my iPod: "Where the Hood At" by DMX.

Proudest moment this year: Being part of Paramount as it celebrated its 100-year anniversary.

Totally starstruck around: Presidents and rock stars.

Best advice I've ever gotten: My dad once told me to make sure I wake up every day and love what I do. I can say that I do.
