Brent Butt began as a stand up comedian, but I didn't hear of him until I started watching Corner Gas. He's the creator and sometimes writer for the show, and stars in it as well, as Brent LeRoy. The idea of the show is just to deal with life's little problems, but in a funny way, and in a tiny town in the middle of nowhere.
He plays the role well, and in interviews, he's certainly made it pretty obvious that he's pretty much playing himself. However, he's also writing some of the episodes, and therefore writing other characters too; and as executive producer, he has a say in all the episodes. It's a great show, and Brent Butt is the driving force behind it, which makes him incredibly talented, in my book!
