On looking into I've found that Donald Gee has been in quite a lot of stuff actually. Stuff that I've seen many times and not even realised it was him as well. I'm usually pretty good at the "spot the minor actor/actress" game.

I quite like his Lestrade as well, once I realised how irrational it was to not like a Lestrade based solely on the fact that the actor is not Colin Jeavons. lol.
