asthma inhalers in movies

I've seen at least one kung fu movie(Bruce Le's Deadly Strike) where the evil big boss's only 'weak spot' is an asthma inhaler(or at any rate some littel doodad he has to breathe from periodically to live, the film being set hundreds of years ago) the heroes have to steal to be able to kill him. I'm sure there are others.

Also Darth Vader!
