NBC has been pretty gracious with the amount of Community video previews they’ve posted online. But this is the first one that has shown more than a few seconds of character interaction in the context of the first episode, “Biology 101,” which premieres this coming Thursday at 8 pm ET. In it, we get a great taste of newly cast John Goodman’s role at Greendale. We also see Michael K. Williams — playing off his former role as Omar on The Wire — addressing his students for the first time. And there’s more. So check it out!
