While filming Mitch and Trey doing promos for Showtime, William Shatner complains that Mitch "is the worst actor I've ever seen". This is an obvious in-joke reference to the criticisms about William Shatner's notoriously "hammy" acting.
There was a scene that was filmed, but cut out to better explain how Mitch could take on Trey as his new partner. In the beginning the film, Mitch goes on an undercover sting with another cop. That was Mitch's partner. He was wounded during the shootout with Lazy Boy. In a scene that followed, Mitch is visiting his partner in the hospital who is in recovery and contemplating retirement.
