THR's Women in Entertainment 2012: Power 100

Her international distribution operation is one of the most powerful in Hollywood, reaching $2.87 billion in ticket sales in 2011 and with year-to-date ticket sales of about $2.1 billion. Warners usually is No. 1 or No. 2 in terms of market share, an enviable feat. Appointed to the post in 2000, Vandenberg, 49, is credited with improving communications with the studio's network of distributors in more than 120 countries. Several films that underperformed domestically made up ground overseas this year, including Wrath of the Titans, which grossed $218.3 million internationally and $83.7 domestically.

Moment I knew I wanted to work in the business: I lived in Hong Kong until I was 11 -- my father was Chinese, my mother was German -- and I remember watching big event films like Sergio Leone's Once Upon a Time in the West. I loved everything.

Who gave me my first big break: [Former Warners president] Alan Horn, when he made me president of the division.

When I leave work each day, I can't wait to: See my husband and children. My daughter is 6, and my son is 13.

My indulgence: Rote Grutze, a German dessert with vanilla sauce over a red-berry concoction.

Can't get through my workday without: A green drink from Pressed Juicery.

Proudest moment this year: When we helped to push The Dark Knight over $1 billion in worldwide grosses.
