Fred Savage (Kevin Arnold)

Now: In addition to playing Number Three, a.k.a. the Mole, in Austin Powers in Goldmember (2002), Savage has voiced roles on kids’ shows, including Generator Rex, Kim Possible, and Oswald. In recent years he’s focused his talent behind the camera, producing and directing numerous episodes of decidedly grown-up fare like It’s Always Sunny in Philadelphia and Party Down.
