Trivia: The Merc sign in this movie can be seen in High School Musical 3, during the 'Boys Are Back' scene. It's missing the letter 'M', but it's the same sign.
Trivia: In the street car, look out for a small boy wearing a hat. This boy is director Renny Harlin's son, Lucas.
Trivia: Despite being the third film, this sequel was actually filmed second. At the point it went into filming, Wesley Snipes, who starred in the original, hadn't signed on for a sequel, so his role was recast. During production, Snipes signed on to return to the series and a new sequel was commissioned, while this film was shelved while producers figured out what to do with it. It was going to be re-titled at one point and any references to the previous films cut-out to make it stand alone, but after "The Art of War II: Betrayal" became a hot-seller, this film was quickly released as the "third" entry in the series.
Trivia: When the Bone Hunters get trapped under the falling rocks, you can hear the Wilhelm scream.
