I realise how ridiculous that title sounds…
My husband swears he once saw a kung fu (other martial arts?) movie which featured a scene in which two characters are fighting (possibly) on a boardwalk, near water. During the fight one paralyses the other with a pressure point move. Meanwhile a fly/bee/flying insect of some sort passes and the paralysed guy blows it so that it hits a pressure point on the first chap. They then blow the insect (or different insects) back and forth at each other.
He would have seen it in the early 90s but it wasn’t necessarily new at that time.
We’ve asked/googled/searched like mad but nothing doing! Help?
