After an early career as a model and commercial actor, Jonathan Taylor Thomas entered millions of homes as the son of Tim Allen's character on eight seasons of the hit show "Home Improvement." In the 1990s, the teen heartthrob voiced young Simba in Disney's THE LION KING and appeared in several movies (WILD AMERICA, TOM AND HUCK, MAN OF THE HOUSE) before taking a break for school… but he never really returned. While he did briefly reunite with his TV dad on the sitcom "Last Man Standing", in recent years an actual JTT sighting is nearly as rare as seeing Bigfoot.
