David Schwimmer

You knew him as: Ross Geller, the angst-ridden, twice-divorced paleontologist and brother of Monica.

Now you know him as: Ummm, still Ross. Despite a voice role in "Madagascar" and guest starring on "30 Rock," he's still Ross.

Where you’ll see him next: In 2007, Schwimmer directed his first film, the British comedy "Run, Fat Boy, Run." He also reprised his voice role in "Madagascar 2" and will appear beside Kate Beckinsale in the thriller "Nothing but the Truth" later this year. (Ollie Upton / Picturehouse)
