24. Zoe Saldana
This half Puerto Rican, half Dominican dime, who played Uhura in Abram's Star Trek relaunch, is the new Intergalactic Empress of the Geeks. We mean that in a totally positive, "we want to explore deep space with her but our phaser just blasted in our pants" kinda way.
DECADE ACHIEVEMENT: She started the decade working with Nick Cannon (Drumline) and Britney Spears (Crossroads). Now she works with guys like Steven Spielberg (The Terminal), J.J. Abrams (Star Trek), and James Cameron (Avatar). Ultimate come up.
