Trivia: California Govenor and former action star Arnold Schwarzenegger makes a special guest appearance in this movie. When Beck first arrives at the night club, Arnold walks right by him and tells him to "have fun." Arnold had just become Govenor and knew he would not be acting for awhile so this was his way of passing the torch to someone he felt would take his place as the future of action movies.
Trivia: The film's original title was "Helldorado." It was then changed to "Welcome to the Jungle," before being changed again to "The Rundown." It's still "Welcome to the Jungle" in Europe, possibly because "The Rundown" sounds like it refers to a car accident, whereas in the US it would be more readily associated with a bounty hunter.
