We've seen Laurence Olivier nationalistic take on Shakespeare before in Henry V, but in Hamlet (1948) he runs a different approach, casting the moodier play in German Expressionism-like starkness. Like any filmed Shakespeare there's a lot of editing from the source material, but the end product is representative of the play, at least Olivier's interpretation of it. But that's how adaptations work, right?
The Peter O'Toole and Orson Wells discussion on Hamlet that we refer to can be seen here. It's a great chat from a group of people who really know what they're talking about but can't all agree.
