When Bone is speaking to James at his home, James asks Bone where he learned how to fight. Bone merely answers, "Here and there." Michael Jai White who portrays Bone, is an avid Martial Artist who began training at the age of 8, holding Black Belts in 7 different styles and 26 Championship titles. His noted styles for holding black belts, are as follows: Kickboxing, Shotokan Karate, Tae Kwon Do, Okinawan Kobudo, Gojo Ryu, Tang Soo Do, Wushu and Kyokushin Karate.
According to the DVD commentary, the scene that used the song "Dance Hall Days" by Wang Chung was meant to use ABBA's "Dancing Queen", but "ABBA wasn't having that".
When Bone (Michael Jai White) reveals his intentions to Angela, she asks if he's her "White Knight." Bone jokingly exclaims, "I don't know about... 'White' Knight." This of course, references the fact that Bone is Black; making him her "Dark Knight." One year prior to making this film, Michael Jai White portrayed the Mob boss Gambol in the film "Dark Knight."
