Afraid that Dax Shepard and Dane Cook resembled each other too much, movie execs asked Shepard to go blonde.
The store the movie is filmed in is the Costco at 1420 N Renaissance Blvd NE in Albuquerque, NM.
Eva Longoria appeared as a Super Club employee named Lily, in a scene filmed as an alternate opening deleted from the theatrical release. The scene is found in the "Special Features" section of the DVD.
Even though all the signage is removed for the store being a Costco, Costco's brand Kirkland Signature, can still be seen on some of the products and signs.
Dane Cook would later wear his Super Club hat in Good Luck Chuck (2007).
