When you see the rugged, bearded face of Zach Galifianakis, your thoughts probably turn to 'The Hangover' straight away. His character is the troublemaker who tends to trigger the gang's regrettable escapades, and we've had a lot of fun watching him do it. Earning that part wasn't a sudden rise to the top for Galifianakis, though - it was the culmination of years of on-screen entertainment work which started with his own 'Comedy Central Presents' show back in 2001.
Because the internet is everywhere these days, you don't need to be on television or in a currently-screening movie to entertain your fans. He's won Emmy Awards for 'Between Two Ferns with Zach Galifianakis,' and that's a show which is only available through the 'Funny or Die' website! You'll still see him at the movie theater though - film roles seem to be coming in thicker and faster for the 5-foot 7 actor than ever before.
