As anticipated, the sixth season of Community, which recently finished airing through Yahoo, will be the show's last, star Joel McHale said in an interview with Metro Weekly.
In response to the question of whether Yahoo might give the show a seventh season, McHale said, flatly, "No. They wanted to. But all of our contracts were up after six years." Although McHale had previously left open the possibility that new contracts with higher pay would be negotiated, it looks like that won't be happening.
Fans of the show will recognize that the show has officially made the "six seasons" part of the "six seasons and a movie" meme the show popularized. There's also still a chance Community will make it to the big screen: as Vulture points out, McHale recently said in an interview with Esquire, "I really do think there'll be a movie."
