During an appearance on [[Norm Macdonald Live|''Norm Macdonald Live'']], Sandler revealed that the role of Jack was originally intended for [[Allen Covert]]. Sandler also lobbied for [[Bob Odenkirk]], a former ''[[Saturday Night Live]]'' colleague, to play the antagonist Eric Gordon, but the studio declined, as Odenkirk was not yet considered a serious actor.
