Aw, thank you! Poul and Silver are still my two favourites as well. I hope you enjoy seeing some more of him! May I recommend the 1970 film of A Christmas Carol and the BBC 1978 Julius Caesar? Also, if you are okay listening to audio and can get hold of things, he's particularly good in that format - I love Big Finish's Doctor Who: Unbound Full Fathom Five, with his as an AU Doctor, their S2 of Jago & Litefoot where he's the main villain, and also as Legolas in the BBC Radio Lord of the Rings, which is a rather lovely production all round.

(If you're definitely hooked, there's even a david_collings community here on LJ. :-)
