Warner Bros. has optioned a Thundercats script by new screenwriter Paul Sopocy to turn the popular 1980s animated series and toy line into a live action feature.
Variety says Warner-based Paula Weinstein will produce through her Spring Creek Productions, along with Dick Robertson and Lew Korman.
Thundercats revolves around a group of humanoid cats (with feline names like Lion-O, Tygra, Panthro and Cheetara) who must flee their planet of Thundera after it's destroyed. Once crash-landing on another planet, Third Earth, they must thwart Mumm-Ra, an evil sorcerer, bent on killing them off.
Sopocy has written the script as an origin story expanding on the major heroes and villains from the animated series, with the plot focusing on Lion-O coming of age as the leader of the Thundercats.
