On The Walking Dead, an actor never knows when it’s going to be his last week on set. It sure looked like Glenn Rhee (played by Steven Yeun) was out of the picture when he was covered by an entire horde of zombies in the most recent season, but then he wasn’t, somehow. But he could’ve been! And in that moment, Yeun (probably) realized just how precarious his spot on the cult-hit show really was, liable to evaporate with a few keystrokes out of the writers’ room. He began to make plans to ensure that he’d be secure in the event of a Walking Dead-less future, and today, those plans have solidified into a new movie role for the in-demand actor.
