Justin Theroux Shows Off Muscles & Insanity In 2003 MUSE Music Video

And you thought Justin Theroux was just Jennifer Aniston’s new man. Nope. Turns out, he’s quite the music video star. Sure we knew he was actor, but I quite like seeing people going at it for four minutes to awesome music. Let’s take a trip back to 2003 when Justin was just a glimmer in Jen’s eye and starring s in the music video for Muse’s song “Hysteria.”

You can check out the video after the jump. Of course the music is awesome–Matthew Bellamy doesn’t just have adorable children, you know–but the video’s storyline is pretty kick ass as well. Justin plays a man in a hotel room obsessed with prostitutes, until he finds one he falls in love with. Shortly after, as Us Weekly put it, he “trashes the hotel room in a sexed-up fit of rage.”

Cue shirtlessness and muscles! Seriously, if that’s the body he still has, I would even start dressing like him to him keep him. Not that I’m saying that’s what Jen is doing. I’m sure she’s more of a “I won’t wear my bra and you will be mine!!!” kind of person.

You can find the video after the jump. Watch it then tell us what you think. Does Justin look super hot? Isn’t the Muse song amazing? Isn’t Jen lucky to hold those muscles late at night? Leave us your answers and more in the comments!
