A.P. Bio Season 4 Trailer Intros Bruce Campbell's "Mr." Mr. Griffin

When September rolls around, classes at Whitlock High will be back in session as Peacock throws open the doors to the fourth season of the Glenn Howerton and Patton Oswalt-starring A.P. Bio. And just in case you think it's going to be business as usual, think again. New looks! New threats! New schemes! And yes, that is Bruce Campbell as the Mr. Mr. Griffin- Jack's (Howerton) dad. Plus, Durbin (Oswalt) needs to keep the school in one piece as a storm nears and something happens involving Jack, a lot of what looks like blood, and Heather (Allisyn Ashley Arm) no-surprising us when she says she has a "go bag" ready to go.

For a look at how the new school year is shaping up, check out the official trailer for Peacock's A.P. Bio, set to premiere on September 2nd:

When disgraced Harvard philosophy scholar Jack Griffin (Glenn Howerton, "It's Always Sunny in Philadelphia") loses out on his dream job, he is forced to return to Toledo, Ohio, and work as a high school advanced placement biology teacher. As he comes crashing into Whitlock High School, Jack makes it absolutely clear that he will not be teaching any biology. Realizing he has a roomful of honor roll students at his disposal, Jack decides instead to use the kids' brainpower for his own benefit. Over time, his students help him realize his dream job might actually be the one he has right now. Eager to prove that he is still king of the castle, Principal Durbin (Patton Oswalt, "King of Queens") struggles to control the force of nature that is Jack Griffin.

Joining Howerton and Oswalt on the series are Lyric Lewis, Mary Sohn, Jean Villepique, Paula Pell, Aparna Brielle, Nick Peine, Allisyn Ashley Arm, Eddie Leavy, Charlie McCrackin, Jacob Houston, Spence Moore II, Sari Arambulo, Marisa Baram, David Neher, Brendan Jennings, Yuyao Deng, Elizabeth Alderfer, Miguel Chavez, and Jacob Timothy Manown. A.P. Bio was created by Mike O'Brien, who writes and executive produces. Seth Meyers, Mike Shoemaker, Andrew Singer, and Lorne Michaels also serve as executive producers. The series is produced by Universal Television, a division of Universal Studio Group, Broadway Video, and Sethmaker Shoemeyers Productions.
