Arnold Schwarzenegger had a few conditions before accepting the role of John Kimble; he wanted Ivan Reitman to direct the film, he wanted a physical fitness theme, and he and Reitman wanted broken homes, child abuse and family life written into the script.
Arnold Schwarzenegger worked with Pamela Reed again in the movie Junior (1994). Reed portrayed a pregnant woman with a big appetite, quite similar to her character in this movie. He also worked with Danny DeVito in Junior (1994), a candidate for the role of John Kimble, but was not given the part due to his height.
In most of his films Arnold Schwarzenegger plays a character of Anglo-Irish descent (Quaid, Tasker, Gibson, Brewer, Trench, Owens, etc.) while speaking with his trademark Austrian accent. This movie contains a rare occasion where the accent is acknowledged and explained within the story rather than simply ignored.
