While on a tour of Scotland I was at Castle Doune where the Rabbit scene of the movie was filmed. Walking up the pathway to the castle we came upon a rabbit nibbling grass. Everyone froze, then grabbing at our cameras to get the pic. It was perfect.
Doune Castle wasn’t open to visitors last time I was in Scotland - but I was on a tour that passed close enough to see it from a half-mile or so away. The kilted tour guide asked the group if anyone recognized it. I responded “Yes, even without the grail-shaped beacon”. :-)
