Zac Goes Sleek And Chic For David Letterman

In case you had any doubt, Zac Efron has definitely graduated from High School.

Donning a chic suit and a sleek hairdo, Zac appeared on the Late Show to promote his first "adult" film (no, not in that way!), Me and Orson Welles.

We're glad he's moving on from his Disney roots, and this film sounds amaze, but wouldn't you rather have seen him dance his ass off in Footloose?
