THR's Women in Entertainment 2012: Power 100

The highest-ranking female executive at Warner Bros., Kroll can bring the horse to water and get it to drink. With the studio crossing $4 billion in worldwide box office for the past three years (an unmatched feat), this year she brilliantly marketed two films that looked tricky on paper: the Iranian hostage drama Argo ($148.7 million and counting) and the male-stripper drama Magic Mike ($164.3 million worldwide). Part of the key team who assembled the morning after the mass murder in an Aurora, Colo., theater during a screening of The Dark Knight Rises, she ably helped navigate the studio's message as the film became its biggest winner of the year ($1.1 billion). Of course, there were stumbles -- Dark Shadows, Rock of Ages and Cloud Atlas -- but with The Hobbit: An Unexpected Journey out Dec. 14, expect Warners, already at $3.5 billion, to go four for four. As in $4 billion.

My big break: Being hired by Turner in Atlanta.

When I leave work each day, I can't wait to: Go home and watch Homeland, Game of Thrones, The Voice or some other show I've recorded on my DVR.

Favorite way to unwind on the weekend: Not being on the phone.

My indulgence: Buying beautiful things.

Can't get through my workday without: Coffee and a gluten-free cookie.

Most surprising song on my iPod: I have every version of [Leonard Cohen's] "Hallelujah."

Proudest moment this year: Waking up and seeing the numbers for Magic Mike and Argo as well as The Dark Knight Rises.

Totally starstruck when: I was at a party where Bruce Springsteen was and could not work up the nerve to go up to him.
