He's faced a 'Bubble Boy,' gone 'Into the Wild,' had a 'Hangover' and dealt with mental illness in 'It's Kind of a Funny Story.' Now Zach Galifianakis is considering some time as a cop -- a deadly, or rather, dead cop in the Universal Pictures' adaptation of Peter Lenkov's Dark Horse comic, 'R.I.P.D.'

According to the L.A. Times' 24 Frames, Galifianakis is currently in negotiations to co-star alongside Ryan Reynolds in the long-gestating film about how the dead fight post-life crime. An acronym for "Rest in Peace Department," 'R.I.P.D.' follows a murdered cop (Reynolds) who agrees to serve with the otherworldly police force for 100 years, if they help him find his killer. Should Galifianakis sign on the dotted line, he'll play the cop's partner, a former gunslinger.

Last year, producer Neil Moritz called it a "great buddy comedy," but now the L.A. Times is calling it a "stylized crime drama." If they're right and the treatment was given an even darker edge, this would allow Galifianakis to move one step closer to dramatic territory.

That would also be one step closer to the long line of funny people who've gracefully danced into drama, whether we're talking Robin Williams becoming an Oscar-winning dramatic actor, Jim Carrey shedding Fire Marshall Bill for the pains of 'The Truman Show,' or the many comedians who have kicked dramatic ass on 'Damages' over the last few years (Lily Tomlin, Darrell Hammond, Martin Short).

Funny, thrilling or somewhere in-between, are you ready to see Ryan Reynolds and Zach Galifianakis enforce the laws of the dead?
