Hulu's upcoming adaptation of Stephen King's novel "11/22/63" has added another familiar face to its supporting cast, with T.R. Knight joining the ensemble.

Knight, who was one of the original stars of ABC's "Grey's Anatomy," will star alongside James Franco in the event series, which centers around a man named Jake Epping (Franco) who finds a time portal and travels back to 1958, and decides to try to prevent the assassination of President John F. Kennedy on the titular date. But Epping's efforts are thwarted by a host of obstacles, including Knight's character, Johnny Clayton.

Per Deadline, Clayton is "a salesman in 1960s Texas who can't quite break up with his estranged wife Sadie Dunhill (Sarah Gadon), even as she falls in love with Jake (Franco). Charismatic but controlling, Johnny confronts Jake in a tense encounter that puts Jake's double life at risk. But there's equal danger in what will happen if Jake and Sadie expose Johnny's own secrets."

The Hulu original series, produced by J.J. Abrams's Bad Robot company, is set to premiere on the streaming service sometime in 2016. Nine hour-long episodes are planned.
