'Always Sunny' Cast Goes Gentle Into That Good Night
And they are quickly replaced. After seven seasons and several twisted adventures, the cast of It's Always Sunny In Philadelphia have decided to hang it up and move on. Or they were fired. Depends who you ask. However, don't worry about missing the loveable screw-ups at Paddy's Pub. The original actors have all been replaced and we doubt you'll even notice the difference. Haley Osment as Mac, Xzibit as Sweet Dee, Andrew Dice Clay as Frank, UFC Fighter Chael Sonnen as Dennis, and Candace Cameron as Charlie. Throw in Alan Tudyk as Rickety Cricket and we're in business.
