I know the one you mean. TD is quite humourous about having his script hijacked
He does seem to take it in good humour, but I think there is still that little twinge of bitterness there. Maybe it's just me, but that's how it seems to come off. I suppose you would be though
The thing is, he considered the rewrites to his script to be terrible at the time (apparantly) and so probably didn't expect the story to go down as well as it has amongst fandom. I think he is probably over it by now though
