gness....I saw Hopkins a few times in M Butterfly, in the West End, in the late 80's and he was mesmeric, but I think that was after he stopped drinking.
Dennis Quilley had an interesting story to tell in his auto-biography, about when he was asked by Olivier to take over in the Scottish play, when Hopkins failed to turn up one night.
ABs rules prevents me from quoting directly from the book, due to the extreme language, but its all here in this link :::

I am not sure if Olivier and Hopkins ever spoke again !
