When Andy and Trish argue in the bedroom, the bed is covered in action figure boxes. Between shots just as Andy leaves, a 'Dracula' action figure box disappears.
For Andy to get rid of the Teen Wolf look, actor Steve Carell's chest hair is really waxed by an actress, who is a non-professional waxer. Because there would only be one take of this disturbingly amusing scene, they set up five cameras - one on his 'friends', one over Andy, one on the waxer, one for wide shots, and one for close-ups of his chest. This scene was not scripted, so when the waxer laughs and Andy's friends are totally cracking up it was for real. Though it was strongly suggested to Steve to first trim his chest hair or to take a pain reliever before the taping, he refused, wanting to have the full cringe-effect caught on tape. In one close-up a bit of blood is actually seen bleeding up to the surface - it is not CGI. It took about seven weeks for his hair to grow back, much to chagrin of his wife, who wasn't crazy about his 'chest smiley'.
