I love this picture. I love all behind-the-scenes set photos but especially this one. "Just lay there and look morose and sexy while bearded and naked from the waist up," is what I hope the direction was for this particular shot.
p.s. I hate to say it, but this is maybe...too buff, Y/N? Yet there's something about Justin Theroux that's indescribably goofy. When I figure out what this is, I will let you know. In the meantime, tip a hat: he's actually really good to dogs.
