George Clooney will make his return to television in a serialized adaptation of "Catch-22," Paramount Television said on Thursday, nearly 20 years after he left hit show "ER" to become one of film's biggest names. Clooney will direct and star in the six-episode series, based on US author Joseph Heller's darkly comedic 1961 novel "Catch-22," for Viacom Inc's Paramount Television and Anonymous Content, shooting in early 2018, the studio said.
