- Luis Guzman's character also produces a clone of the Atlantean Sword from Conan the Barbarian from the weapons stash before being discouraged from using it by Arnold.
- Johnny Knoxville's character climbs a telephone pole that soon falls over, among other antics.
- Box Office Bomb: Despite being Arnold Schwarzenegger's comeback film after a decade away from the big screen (not including cameo appearances), the movie has been a financial disaster, barely coming in 10th place at the box office on opening weekend. However, it has gotten generally favorable reviews from critics and audiences alike, so time will tell if it becomes a Cult Classic.
- Hey It's That Guy: Honey Lemon was an FBI agent before becoming a superhero.
