It’s Always Sunny in Philadelphia returns for its eighth season on Oct. 11, and they have decided to switch up the entire cast, at least that’s what the commercials for the upcoming season suggest.

FX has released spoof commercials, and behind-the-scenes footage, with new actors and actresses playing the main characters. Among them is controversial MMA star Chael Sonnen, who will be playing the role of Dennis. Sonnen, whose role likely stems from UFC now being on FX, might be the realistic fit. The other fill-ins are Xzibit as the new Dee, Haley Joel Osment as Mac (actually this is the best fit), Candace Cameron as Charlie and Andrew Dice Clay as Frank.
