I show clips of that film version to my theatre appreciation class when we cover the play. Ms. Dench's costume consists of body paint, glitter, and three well placed leaves (and that's it). The current print available on DVD is not a good print, but it is an excellent cast, and what it lacks in cinematography it makes up for in great actors. I really wouldn't have thought of it as terribly disco so much as "of its time." if you can see if for cheap, and enjoy shakespeare, it is worth your time.
