Seven Samurai
I can't be bothered to wade through 22 pages to see if someone has listed it, but honestly this is tops. Also other Kurosawa films:

Throne of Blood (Macbeth in Japan)
Ran (King Lear in Japan)
High and Low - best police movie ever made

And a couple of others I have recently seen and enjoyed:

The Lives of Others, about the Stasi in East Germany
Apocalypto - just plain astonishing.

If you like Kurosawa films
check out Yojimbo - it's another classic of his.

www.imdb.com/title/tt0055630/

It was remade a few years later in the US and called A Fist Full of Dollars :)

Seen it
But when the treatment is by Shakespeare it's a couple of steps above ordinary. Thanks for the tip, though
