Jack Black stars as "Jerry" Credit: New Line

Actor/musician Jack Black isn't exactly a "Jack" of all trades but close. He plays a mean guitar and his funny songs rock out when he's part of the musical duo (with Kyle Gass) Tenacious D. We all know he can be both hilarious (School of Rock, Nacho Libre) and serious (The Holiday, King Kong) as an actor and he admits that he's a changed man since becoming a dad.

This week you can catch Jack in the very quirky comedy Be Kind Rewind in which he co-stars with Mos Def. The two are involved with an old-timey video rental store and, when all the tapes get erased in a freak accident, the duo decides to just re-shoot all the movies... on a below-low budget and starring them and the whole neighborhood! This process is called "Swedeing" in the film. The results are hilarious.

We chatted with affable Jack recently in Beverly Hills and he cracked us up! We noted his beard and new "do"; very short hair heavily streaked with blonde. Very different.. ..just like Jack.

TeenHollywood: Okay what's with the tinting?

Jack: Yes, I've been tinted. Highlights. This was a full blonde hairdo and it's just growing out. I haven't dyed it back to the original darker brown because I'm lazy. I just don't want to use any more chemicals if I don't have to. And it looks stylish right? It looks like I went to Vidal Sassoon.
