The Russo Brothers take a break from the Marvel Universe to hop on the production side of another comic book series. Based on the graphic novels written by Rick Remender, the show will follow Marcus as he begins training in an underground school for aspiring assassins. But it's not the only interesting bit coming to SyFy. A space-heavy George R. R. Martin adaptation is also in the works. Deadly Class will premiere in 2019 while Nightflyers beings this fall.
