Born in Japan and raised in Montgomery, AL, actor Glenn Howerton attended Juilliard before making his screen debut in the 2002 made-for-television feature Monday Night Mayhem. Recurring roles in That '80s Show and ER found Howerton settling into a comfortable small-screen schedule in 2002 and 2003, with supporting parts in such features as Serenity and Crank coming along just as Howerton joined the cast of the monumental FX comedy series It's Always Sunny in Philadelphia. In addition to his acting duties on the show, Howerton also served as writer, co-creator, and producer of the series. He would also take on regular roles on Unsupervised and lend his voice to The Cleveland Show.
