Biography
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. ~ Jason Buchanan, All Movie Guide
