New York-born actor Charlie Day appeared in an impressive array of Williamstown Theatre productions before transitioning into television with a brief appearance in the Mary Tyler Moore/Valerie Harper reunion special Mary and Rhoda. Subsequent roles on Madigan Men, Law & Order, and Third Watch helped Day build an impressive list of small-screen credits, and in 2005 he joined the cast of the deliciously warped FX sitcom It's Always Sunny in Philadelphia. Cast as an inherently good-natured guy often done in by his own shady intentions and poor luck with ladies, Day held his own opposite Danny DeVito, helping to establish himself as a respectable rising talent. Although he tried to stretch out in projects like A Quiet Little Marriage and Going the Distance, it was the 2011 hit Horrible Bosses that earned him his greatest praise apart from It's Always Sunny in Philadelphia. In 2006 he married his Philadelphia co-star Mary Elizabeth Ellis.
