Get ready, Vought International: Negan is about to come calling. Jeffrey Dean Morgan, known to many comic fans as the primary villain of AMC’s The Walking Dead, has signed on for the fourth season of Amazon Prime’s acclaimed series based on the Garth Ennis/Darick Robertson comic.

Just who Morgan is going to be playing on the show, which stars Karl Urban, Jack Quaid, and Antony Starr, is being kept under wraps for now. He’ll be joining a long line of recognizable faces guest-starring on the show, including Patton Oswalt, Simon Pegg, Paul Reiser, and Jensen Ackles, who joined the show for its third year as Soldier Boy, an analog of Marvel’s Captain America. This will be Morgan's fifth appearance in a comic book adaptation, following his roles in The Walking Dead, Watchmen, Jonah Hex, and Batman v. Superman: Dawn of Justice.

The Boys – which has Eric Kripke, creator of the CW’s Supernatural (which also featured Jeffrey Dean Morgan and Jensen Ackles), as its showrunner – launched on Amazon Prime in 2019, and has become a critical hit for its approach to satirizing both the superhero genre and American politics. In addition to its upcoming fourth season, the show also has two spin-offs expected in 2023: a second season of the animated anthology The Boys: Diabolical, and Gen V, a live-action series set in a superhero college run by the franchise’s untrustworthy mega-corporation, Vought International.

The news of Morgan’s casting was initially reported by the Hollywood Reporter.
