FX has been teasing It's Always Sunny in Philadelphia fans as of late, with a series of videos showcasing an all new cast, including Haley Joel Osment as Mac, Xzibit as Sweet Dee, Candace Cameron Bure as Charlie, Chael Sonnen as Dennis, and Andrew Dice Clay as Frank. The network has released four banners and another intriguing video showing the "old cast" being removed from a billboard, and the new Paddy's Pub gang replacing them. I'm not completely sure why, but every cast member, old and new, has blonde hair in these images. Check out the banners and this bizarre video before Season 8 debuts Thursday, October 11 at 10 PM ET with "Pop-Pop: The Final Solution".
