Happy Birthday, Keanu Reeves! Unbelievably, the actor turns 50 today-- and he's ringing in the milestone with a bang! The star, who has famously starred alongside Hollywood heavyweights like Sandra Bullock (Speed and The Lake House) and Diane Keaton (Something's Gotta Give), has signed on to star and serve as executive producer on the new TV mini-series, Rain. Although we don't know what's in store for Reeves in this new decade, one thing's for sure: he sure has come a long way since his Bill & Ted days!
