Finally got around to seeing it.
It's a pretty good movie. As an adaptation of the book, well, there are a lot of changes, some of which work and help keep the film moving along and at a reasonable length, while others really don't.
Naturally, I'll list my quibbles here. You want the good stuff, buy your own copy and watch it.
The prisoner being called by his proper name prior to his execution: I don't really see any good reason for this, and it messes with the scam.
Sgt. Angua: just plain wrong. Look, everybody knows there's a werewolf in the Watch, but everybody also knows that it's Cpl. Nobbs, OK? How's that work if Angua goes around looking and acting blatantly lupine, never mind changing forms in public with witnesses around? And why would she use the wolf to apprehend a famously nonviolent confidence trickster?
Divine intervention: I suppose it needed streamlining, and the bit with the sausages is good, but having the miracle unambiguously attributable to Offler seems to lose something, and not just the opportunity to introduce Anoia.
The challenge: really, having the message supplied by a third party works much better. Having Moist choose it? Not good at all.
Losing the cat and the cockatoo is, I guess, no big deal; they were kind of nonessential characters. But if the little doggie is missing from the sequel, I'll be annoyed.
And what was the name "Gladys" doing on the Golem Trust chalkboard, when the Gladys subplot had been edited out?
