10 Guest Stars We Want To See It's Always Sunny In Philadelphia
4. Danny McBride
Some people can truly make a living out of playing obnoxious, unlikeable characters, and Danny McBride is one of those people. The talented comedy actor has made a name for himself in a litany of TV and movie roles, with some of his most iconic being Pineapple Express, This is the End, Eastbound & Down and Vice Principals. It's doubtful that you haven't caught something with him in it.
Part of what makes McBride so amusing is how he can charm you into rooting for him even when his characters are acting like tools. Thus, it's hard to think of somewhere better to place him than Always Sunny, where almost every character is doing something awful most of the time, yet you still love them.
There are plenty of places to put him, as McBride is a very versatile actor. It would make sense to see him go up against the gang as some fresh enemy, as seeing him riff against them would make great use of McBride's well-known improvisation skills.
He's an effortless pick and would undoubtedly capture the vibe of the show well.
