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.
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.
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.
