Currently, Diablo Cody(Juno) is set to produce the script by Geoff Latulippe (Going the Distance). Joseph Gordon-Levitt filming "Live with It" in Vancouver, Canada, March 17, 2010.

Browne’s novel is described as a romantic comedy about a dead man named Andy who finds himself brought back to life as a middle-aged zombie. Andy must then “figure out it means to live as an Un-dead in a society that denies his kind basic rights.” I’ll trust you to interpret the metaphorical social commentary from there. If cast, one would assume that Gordon-Levitt would portray Andy with Johansson playing Andy’s love interest (hence the “romantic comedy” description)". Source:
