An active child star, Jason got his start at age 11, playing A. J. Quartermaine on General Hospital (1986-88) and werewolf-boy Eddie Munster on the remake of the classic 1960s tv series The Munsters (1988-91).
Eerie Indiana (1992), Perry King in Almost Home (1993), Brandon Call (left) on Step by Step (1993-98), Will Friedle on Boy Meets World (1994-95), Boomer Bridges in White Squall (1996), and Robert Downey Jr. on Allie McBeal (1997).
In a 2002 episode of Will and Grace, he plays "the pocket gay," who is rejected by Will for being too short but eventually wins him over.
Max Goof, surly teenage son of Disney's Goofy in Goof Troop (1992-3), two movies (1995, 2002), and House of Mouse (2001-2002), for some reason a gay fan favorite and the subject of lots of homoerotic slash fiction.
Burt Ward, Batman and Robin from the 1960s tv series. As the young Burt Ward, Jason displayed an impressive muscular physique.
He also looked impressive below the belt, but that may have been necessary to the plot, which devotes a great deal of time to the censors fretting over the Boy Wonder's massive endowment.
