Really weird coincidence
I've just watched "Merlin" for the first time. And since I'm good at spotting faces, I saw two people in it who also made an appearance in "Excalibur" (1981). They are Nicholas Clay, who played Lancelot in the older movie, and Robert Addie, who portrayed Mordred in the same.
It gets odder when you find out that both these stars sadly passed away at a young age with cancer in the last few years; Nicholas Clay in May 2000 aged 53, and Robert Addie in November 2003 at 43.
