They've Got the Power!

Eureka! This year, we bring an entirely new level of scientific accuracy to our 14th annual Power List. In fact, we've come up with a formula that says it all about who rules Hollywood: Power = Control + Bankability + Influence x Heat. (In our new physics, heat is the most unstable element of all -- the quality that gets people talking about you.)

Lucky for you, there's no need to consult some boring science journal to figure out who's using this formula to dominate showbiz. We've got all the facts right here. Click through the following gallery where we present our selected favorites -- including Nicole, Eminem, and Beyonce -- from this year's list of 101 most powerful people in showbiz.
