Stephen Briggs would like to play Vetinari in a movie and yes, he does act. He wrote the scripts for several books so that they can be done on the stage and he is involved in a theatre company. He portrays Vetinari at the Conventions and he did also at the town twinning at Wincanton in 2002.

Pictures of Vetinari are very like Briggs but I'm not sure which came first. Apparently Briggs was upset a bit because he didn't get a part in Hogfather but then the Patrician wasn't in it.

Briggs also produces DW merchandise on a website as stephenbriggs.com cmot dibbler
