During a 2014 interview on Gilbert Gottfried's Amazing Colossal Podcast, screenwriters Scott Alexander and Larry Karaszewski revealed that the studio was reluctant to rehire them, only doing so because they wanted to shoot a sequel before Michael Oliver could noticeably grow and, as the writers of the first film, could produce a script quicker than writers new to the story and characters of the franchise. Frustrated with the criticisms of Problem Child (1990), they deliberately increased the poor taste in the sequel, intending to make a Pasolini or John Waters film for children, and went so far overboard that the first cut received an R rating from the MPAA, a secret kept until their 2014 appearance on the podcast. Dubbing over Junior's use of the term "pussy whipped" got the film a PG-13 rating on appeal but the studio was still so nervous that, at the last minute, they added the Woody Woodpecker cartoon Smoked Hams (1947) to the film's theatrical release to reassure parents that the film was suitable for children.
The action figure that Junior electrocutes in his science project is modeled after The Bow Tie Killer from the first movie.
Ben is still driving the Jeep he "borrows" from Roy in the first film when he goes to rescue Junior from the Bow Tie Killer.
