Another British TV production of a Terry Pratchett novel. Moist von Lipwig (Richard Coyle) is a rather good con man, but is ultimately caught by The Guard of Ankh-Morpork and sentenced to death. He awakes after his hanging to find the Patrician (Charles Dance) offering him a choice between restoring the Post Office or a rather more permanent death. Being a sensible man, he chooses the Post Office.
I read the novel several years ago and didn't think it was one of Pratchett's best. They've come up with an acceptable adaptation, but, like the source material, it's simply mildly amusing (and I rather wonder if it would work for non-Pratchett fans). Pratchett himself puts in a short speaking cameo at the end of the film as a postman.
On second viewing my take is a bit different. I still don't think it's a particularly good movie, but I quite enjoyed it anyway.
