is it a kind of dream?

OK so i know that Andrew Burt (Stanislaus Oates) played Valgard from Terminus. There's been one or two others I've recognised as well. But Flowers for the Judge seems to have Damon from Arc of Infinity in it as well as Rassilon from The Five Doctors - I'll know for sure when the credits roll, but GOSH are they familiar....

Its so interesting to see them in a role where they're being deadly serious, and not hamming it up for a kid's show.. Very interesting indeed.
