THR's Women in Entertainment 2012: Power 100

Since taking over in 2000 as head of the group that puts on the annual American Film Market, Prewitt, 64, has grown the organization's mandate and outreach. She has made IFTA a global voice for independent buyers and sellers. That included a role in the U.S.-China movie deal struck in early 2012, the battle against piracy of intellectual property, net neutrality and other issues.

Moment I knew I wanted to work in the business: In 1976, I was offered the choice by my New York law firm of going to Rochester, N.Y., to do document searches on an antitrust case, or going to L.A. with a tax team to represent Universal.

When I leave work each day, I can't wait to: Pick up my Australian cattle dog from the kennel.

Favorite way to unwind on the weekend: Read murder mysteries.

One indulgence: Electronics -- iPads, iPhones, computers. And I cannot be stopped from acquiring books on Kindle.

Can't get through my workday without: Twizzlers.

Proudest accomplishment this year: Three women who were interns for me in the 1990s have ended up with high-level government appointments.

Totally starstruck around: Michelle Obama.

Embarrassed to admit that I watch: America's Next Top Model marathons.
