The erotic dance between Steve Carell and Tina Fey was improvised, but to make them feel awkward in character, director Shawn Levy shouted obscenities to them while behind the camera.
Despite the fact that his character's minimal apparel is a running joke throughout the movie, there is a dedicated wardrobe assistant to Mark Wahlberg listed in the end credits.
In all of Mark Wahlberg's scenes, he is shirtless. His scenes were carefully filmed at specific angles to avoid showing a tattoo of Bob Marley that he has on his right shoulder.
In the scene where Claire Foster (Tina Fey) is preparing for bed, she is shown wearing a University of Virginia t-shirt. Tina Fey graduated from there in 1992.
