A man of the stage, he was a member of the Royal Shakespeare Company from 1966 until 1982, though he remained (relatively) unknown until he sat in the Captain's chair on the bridge of the Enterprise-D in Star Trek: The Next Generation.
bad Funk, you lose total geek points with that statement
he was Gurney in Dune, Leondegrance in Excalibur and Sejanus in I, Claudius before doing Star Trek. he was also the most awesome King Richard in Robin Hood Men in Tights, beating out Sir Sean in the Kevin Costner version of Robing Hood
as for some Patrick Stewart specific Star Trek trivia.
he would often wear a beavis and butthead shirt under his uniform or other odd type shirt.
if you watch he always straightens out his uniform by pulling on the bottom of the top because he hated having creases in it. Jonathan Frakes dubbed this "The Picard Maneuver"
