Rain,
You might want to check out Sir John Guilgud's 1964 version with Richard Burton, which is on DVD. I little unique, in that it's only a practice in street clothes, but still a screen version of the play.
People criticize the Branagh version, but I agree, it's great to have the entire play for once. And I'll say it again, Zeffrelli's version was quite audacious in changing scenes around. I'll have to dig out my (ugh) VHS tape sometime and go through it again, but I did this about 5 years ago, and had to skip around in the text while following Gibson lust after his Gertrude. There were some notes I read once, that said Zeffrelli did this to increase the momentum of the play for his adaption.
