Whether it expresses befuddlement, exuberance, or just plain goofiness, Jack Black's countenance is one of the most expressive and distinctive in contemporary movies. With Year One hitting theaters this week, we at RT thought it would be a good time to take a look at the many faces of Black.

Bob Roberts

Even in his debut movie role, the political satire Bob Roberts, Black had already perfected his patented mugging. And as with later roles, he played a young man who paid tribute to his musical heroes, in this case, the folk singing right-wing politician of the title.

High Fidelity

In High Fidelity, Black nearly stole the show as a vulgar, hyper-opinionated record store clerk. However, it was his relatively straightforward (but still plenty ribald) rendition of Marvin Gaye's "Let's Get it On" that brought this occasionally wistful meditation on modern love to a soaring and satisfying close.

Saving Silverman

Black and Steve Zahn will do anything to keep their best buddy from tying the knot in Saving Silverman. And by anything, we mean anything. Black's character, J.D., is motivated by a similar urge as many of the actor's other characters: to keep the band (in this case, a Neil Diamond tribute group) together at all costs.
