I assumed that they would have hired actual disabled people to star in this and expected it to be a little more tasteless than it was. Alas, the lead "cripples" are all played by actual abled kung-fu masters. They do show a child having his arms off, so there's that. It also features a man being turned into an idiot through head compression. Apparently rudimentary medical science isn't really that big in Hong Kong. The main focus here is acrobatic fighting with hoops, chains and poles. The disabilities don't really play into the fighting styles beyond the initial training montages.
