12 Best It's Always Sunny In Philadelphia Guest Stars
11. Jason Sudeikis
Very rarely has a guest star blended so seamlessly into a show as Jason Sudeikis on It’s Always Sunny in Philadelphia.
Sudeikis is Schmitty, once a member of the gang, he was forced out by Charlie with the gang unable to remember why. After Mac, Dennis, Frank and Charlie track him down he becomes part of the gang once more, rankling with Charlie who feels like he has lost the attention of the others. With Schmitty seeming like an upgrade on Charlie the gang opt to transition from Charlie to Schmitty.
However, Schmitty subsequently begins to take issue with the gang’s peculiarities and idiosyncrasies, such as Dennis choosing everyone’s lunch and the gang’s surreal welcoming ceremony. With the status-quo well and truly shaken the gang decide to re-replace Schmitty with Charlie.
Sudeikis actually reprises the role briefly at the end of the High School Reunion episode wherein he steals the Waitress from a dumfounded Charlie.
Seemingly, Day and Sudeikis’ darkly comedic exploits in Horrible Bosses primed the actort for the depraved, heinous world of It’s Always Sunny in Philadelphia.
