Bob Barker wasn't sure if he wanted to be in the movie. When he learned that he was going to win the fight with Adam Sandler, he accepted the role.
Whenever Mr. Larson is on screen, he either stands still or leans on something. In 1992, Richard Kiel was in a serious car accident that left him unable to balance unassisted.
When Dennis Dugan told Bob Barker that a stunt double would be used in the fight scene, Barker insisted on doing his own stunts, saying, "Wait a minute, I know how to fight."
In a 2011 interview with the AV Club, Christopher McDonald said he originally turned down the role of Shooter McGavin several times because he was growing tired of being typecast as an antagonist. He reconsidered the role because he had enjoyed Adam Sandler's previous film, Billy Madison (1995), and he was playing a golf tournament in Seattle while taking a break from filming his previous movie in Vancouver. Realizing that he was playing an antagonist in a comedy, and satisfied with the script, he asked to meet with Sandler to discuss the movie. Upon their first meeting, McDonald decided to accept the role. He said it remains one of the best decisions of his career.
