Tyrese Gibson may be doing a live action movie of the thundercats? Maybe he will be Liono. But i really would like to know who is going to be Cheetara. “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.
