Review of Hamlet at Elsinore

I am looking for a copy of Christopher Plummer as Hamlet at Elsinore, my aunt watched it when it was shown on TV in the UK in 1964, and said it was the best version of Hamlet she had seen. I am studying at drama school, and very interested in obtaining a copy for her and myself. It seems the BBC over here has not produced copies, and I suspect they have recorded over it with the pathetic programmes that are shown today. If anyone has any idea of how I might go about getting a copy of this, I would be extremely grateful, I saw on one website it was in a museum in New York. Can you get copies from there?

Thanks a lot, Annamarie
