Ice Cube: Jill Greenberg/Corbis Outline

Ice Cube

Age 34

The rap pit bull who barked ''F--- tha police'' in 1989 is a Hollywood mogul in 2003. In 14 years, he's starred in 20 movies, written six, produced nine, directed one, and sealed development deals at three studios. Last year, his Cube Vision company produced ''Barbershop,'' a low-cost/high-yield hit that has spawned a sequel and a spin-off. And speaking of franchises, he'll replace Vin Diesel in the ''XXX'' sequel. The only area in which his power seems to be waning is music; side group Westside Connection's album (Cube's first in three years) comes out in December.
