Bryan Singer is currently in production on X-Men: Apocalypse, and while that’s a pretty consuming job, he’s already making some post-X-Men plans. His first project following completion of the superhero trilogy will see him teaming up with Arrow executive producer Marc Guggenheim for an adaptation of the classic Robert A. Heinlein sci-fi novel The Moon Is a Harsh Mistress.

THR reports that Singer will direct the adaptation for Fox, while Guggenheim will provide the script based on Heinlein’s novel. The film will ditch the lengthier title in favor of the more simplistic Uprising. Heinlein’s novel, first released in 1966, tells the story of a lunar colony’s uprising against the people of Earth, who maintain control over the colony. Heinlein also wrote the novels that inspired The Puppet Masters and Starship Troopers, and the short story upon which Predestination is based.

Heinlein’s The Moon Is a Harsh Mistress is a tricky story to adapt, though it’s been attempted twice before: DreamWorks had a script by Ted Elliott and Terry Rossio, while Phoenix Pictures had Harry Potter producer David Heyman involved in plans for their own adaptation.

It remains to be seen whether Singer will return to the world of X-Men upon completing Apocalypse, but producer Simon Kinberg has previously revealed plans for an X-Men film universe similar to that of Marvel, so it’s likely that we’ll eventually get another installment in the franchise at some point.

X-Men: Apocalypse hits theaters on May 27, 2016.
