Nimoy is a superb actor - and I want to put him in somewhere, but I have not got it right yet.

I think Clint Eastwood (from the early "Rawhide" days) might be better as Greebo - Greebo has to be big and to have that catlike grace. If you just want burly and evil maybe the young Oliver Reed, but he always had trouble with grace.

What's the name of that Irish actor who does the sinister psychotic undercover policeman (and the hammy TV ads for yellow pages)? He might be good for Vimes - and he is small enough too. Don't forget Vimes has to collapse under the weight of Lady Vimes (pre-wedding) when rescuing her from the dragon.

The fat tenor (is it Harry Sugg?) - Rik Waller surely (or Meatloaf).

What about David Suchet for Dr Downey? Or he could probably do the trick of disappearing so as to be Moist Von Lipwig.   Another wholly superb actor.

I am however amazed that there are those who dispute the casting of Vetinari - it simply HAS to be Ian Richardson.

When we get to "Soul Music" I have an acting role for Pete Docherty!

Maybe Roy Kinnear for the Dean?

Off to continue the re-reading now....
