The title was originally Meals on Wheels but the box office flops of Megaforce and Menage A Trois forced the change to avoid a third film with a "M" title. The producers were very superstitious and didn't want another box office failure. The film was a huge success.
Action scenes were directed by Jackie Chan, Chin Ka Lok, Mars, Sammo Hung, Paul Wong, Benny Lai and Danny Chow.
Benny Urquidez was almost fired from the set because he couldn't pull his punches.
This is probably the most important film I ever watched. I saw it on TV when I was a kid, it was my first Hong Kong movie and also the first time i'd ever seen martial arts. I was fascinated, I still am fascinated.
