Seinfeld alum Jason Alexander will be playing an unknown role in an upcoming episode of Community. Alexander revealed his guest role via Twitter, writing “Filming a crazy episode of COMMUNITY this week. Can’t say much about it but it’s a fun one.” Alexander’s episode airs in late spring, and Community returns to NBC February 7th. That tweet is all the info we have on Alexander’s guest spot, but blogs like Zap2It have begun speculating that he’ll be replacing recently-departed Chevy Chase as a gag for one episode, which actually sounds pretty plausible for Community. Jason Alexander, like Chase, is a beloved comedy veteran so there are a lot of similarities there, although I think he would make a much better replacement for the character Magnitude.
