School is in session, and this time, A.P. Bio's Glenn Howerton is the student!
The It's Always Sunny in Philadelphia funnyman returns as favorite sarcastic teacher Mr. Griffin in season four of Peacock's A.P. Bio, back Thursday, Sept. 2.
The beloved ensemble cast also includes Patton Oswalt, Paula Pell, Jean Villepique, Lyric Lewis and Mary Sohn, plus a few surprise celeb cameos. But this season, one fresh face even took Howerton by surprise—especially when he was playing Howerton's onscreen father, "Mr. Mr. Griffin."
"Bruce Campbell is a childhood hero of mine," Howerton exclusively gushed to E! News on Aug. 27. "I'm not being hyperbolic. Evil Dead 2 changed my point of view, like it made me realize that things were possible. I was like, 'Oh, if you can do that, you can you can do anything, as long as you got the ability to pull it off.' He was just so influential to me as a child. I was honored, and he was great. He was super fun to work with and a sweet guy. It was just a pleasure."
Joe Manganiello also guest stars as Malikai, or as Howerton describes, "a manic anime, hentai-obsessed, former inmate, who is kind of in love with the girl that is playing the girl that I'm dating."
Howerton and Maganiello kept in touch IRL after first collaborating on Archenemy, and Howerton called working again with the "incredibly talented" Magic Mike XXL star a "no-brainer."
"He hasn't done a lot of comedy but every time I've seen him do something funny he's always really funny," Howerton gushed. "He's great."
These wacky side characters embody what showrunner Michael Bryan aspires to capture in the "surreal" sitcom, as Howerton noted.
As Oswalt added, "The show is able to be both absurd and also you just really love these characters."
