Not sure why you were thumbed down. Brook's production is by far the best put to film (unless one is willing to count Kurosawa's Ran). Scofield is menacing and pathetic, but not beyond sympathy. The set design choices bring out the cold, unforgiving politics of pre-Christian Britain. This is especially true of Kent's night in the stocks which is portrayed with a moving brutality not found in other portrayals. 

Unfortunately, this production was never released in the US. To watch it, one must purchase a UK copy AND purchase a DVD player encoded for UK-only releases. I own such a copy, but had to run the file through several programs to make the file region free. It's probably too big to email, but if anyone is interested send me a pm and I will see what I can do. You'll have to watch it on your PC or burn it to a DVD.
