What do you do when you find two martial arts experts who are missing a few limbs each?  Why, make a movie where they seek revenge for their mutilations, of course!

There's some excellent and unusual kung fu on display in this one, together with a slightly uncomfortable sounding voice-over.  The protagonists seem anything but crippled, leaping about the place and beating the crap out of various bad men.

I don't understand the segments with the Yoga expert in the box.  Perhaps he's their spiritual adviser or something?  That doesn't explain why they meet him on a really plain-looking studio set.

So...  Is this film an uplifting tale of triumph over adversity, or base exploitation of people who have worked hard to overcome physical disabilities?  I suppose you'll have to see the full version to find out, but given that it was made in 1979 it's unlikely to be the former...

Favourite bit:  Right at the end, where the guy with no legs suddenly flies up in the air and teleports for no discernable reason.
