Zach Galifianakis Joining Reynolds in R.I.P.D.?

24 Frames is reporting that Zach Galifianakis (upcoming The Hangover Part II) is in talks to join Ryan Reynolds in the Robert Schwentke-directed R.I.P.D adaptation at Universal Pictures:

Galifianakis is in talks to play the co-lead in the film, according to two people with knowledge of the project who were not authorized to speak publicly about it. The movie is based on a popular Dark Horse comic about dead police officers patrolling the underworld.

Peter Lenkov created the comic -- the acronym stands for Rest In Peace Department -- which centers on the revenge sought by the recently murdered policeman Nick Cruz (Reynolds). Galifianakis would play another dead police officer.

According to the site, the studio is planning on a summer start. Matt Manfredi and Phil Hay wrote the script.
