Try to look into those cocked-eyebrows and tell us he doesn't look like he'd peel off your face and wear it as a mask.  This 'serial killer' statement was shared by none other than Justin Theroux's beau Jennifer Aniston, who was describing about his killer good looks (via NY Daily):
The actress reveals to Pop Sugar that she didn’t immediately fall for her boyfriend’s killer good looks when they first met on the set of “Tropic Thunder” in 2007.

"I met Justin about five years ago and I thought he was so sweet and very nice," Aniston, 43, told the website. "But I remember thinking he was very dark. At first you think he could be like a serial killer, but he’s (actually) the nicest person in the world."
