In 2012 it was reported that Guillermo del Toro and Charlie were once thinking about adapting the Vonnegut classic Slaughterhouse Five, and in 2013 it was reported that del Toro hadn't entirely given up on the idea. Now Variety reports that a Slaughterhouse series has landed at Epix and neither of those guys are involved.
Universal Cable Productions’ “Slaughterhouse-Five” series is now in development at Epix, Variety has learned exclusively.
Based on Kurt Vonnegut’s classic novel of the same name, the project focuses on Billy Pilgrim, a WW2 soldier who becomes “unstuck in time” and travels back and forth through his past, present and future. The novel explores the idea of predestination versus free will, the impacts of war, as well as the perception of time itself.
UCP will produce. The series hails from writer and executive producer Patrick Macmanus, who is currently the showrunner on “Happy!” at Syfy. Gale Anne Hurd of Valhalla Entertainment will also executive produce along with Jon Brown of Ensemble Entertainment and Bradley Yonover of Brand Y Media. Kari Skogland, who recently secured an Emmy nomination for her work on “The Handmaid’s Tale,” is attached to direct. (Source)
Which doesn't rule out a Kaufman adaptation, but it doesn't exactly increase the likelihood, eh?
