Hamlet in performance

[CluBu]

I'm looking for the details of a particular performance of Hamlet, in which the play both started and ended with the words 'Who's there?'. It was mentioned in a lecture I attended a couple of weeks ago but I've been unable to get in contact with the speaker.

Anyone have any ideas?

My Arden edition (2006) tells me that Peter Brook's 2000 adaptation ends with 'Who's there?' and - although it doesn't say - I presume it also opens with this line as usual.

Any help?

The most help ever! This is brilliant - thank you so much!
