Comedian Zach Galifianakis has snagged lead roles in Todd Phillips’ comedy “The Hangover” for Warner Bros. and the HBO pilot “Bored to Death.”In “Hangover,” Galifianakis, Bradley Cooper and Ed Helms play best buddies at a wild Las Vegas bachelor party who lose the groom just hours before his wedding. Legendary Pictures is producing with Warners, and filming is set to begin this weekend.

In “Death,” Galifianakis plays Ray, a struggling comic book artist and best friend to Jonathan (Jason Schwartzman), an alcoholic writer who pretends to be a private detective. Ted Danson also stars in the project from writer Jonathan Ames and director Alan Taylor.
