As a big Terry Pratchett fan, I was pretty psyched to find The Colour of Magic (2008). Discovering that the cast included Sean Astin, Tim Curry (recently deceased at time of writiing), Christopher Lee and Jeremy Irons was just a bonus.
To start off, the story takes place on Discworld, a flat planet perched on four elephants, on the back of an enormous space turtle named A'Tuin. Scientists on the edge of the world are studying A'Tuin, and are planning to launch an extra-disc space expedition to determine A'Tuin's sex. This will become important later.
We now come to Ankh-Morpork, the disc's largest and most corrupt city. David Jason plays Rincewind, the most inept wizard in the Unseen University. We meet him as he is being expelled. While he is failing to commit suicide, he runs into Sean Astin, playing Twoflower, a Discworld's first tourist. As a tourist, he wears a bright tee-shirt and speaks slowly and loudly. He also has a trunk on feet made of Sapient Pearwood that is filled with gold coins. Rincewind quickly signs on as his tour guide.
At the university, the wizards are all vying to improve their standing in the hierarchy, and the only way to move is "dead man's pointy shoes." Assassination abounds, and Tim Curry, Trymon, is an expert, aiming to become Arch-Chancellor. One thing he'll need it to master the greatest spellbook in the disc, the Octavo. The problem is that one of it's eight spells is gone. It lives in Rincewind's head. In fact, it fills his head to the point that he can't master any other spells. That's why he was expelled.
So, Rincewind and Twoflower are running around the disc, Twoflower trying to see the sights, Rincewind trying to stay alive. But as a tourist, Twoflower is strangely impervious to danger, and the spell in Rinceworld's head seems to protect him. He keeps running into Death, but not dying. They get accidentally launched into space (as mentioned). They run into the most feared man on the disc, Cohen the Barbarian (David Bradley, now old and toothless, but deadly as ever. He even rescues a beautiful virgin from being sacrificed, Laura Haddock.
But there seems to be an evil red star in the sky, and it's getting bigger. If only the wizards had control of the eight spells in the Octavo to save Discworld. Oh, well.
This "movie" is actually a two part series by the BBC, directed by Vadim Jean. He also directed the earlier Hogfather. That is a "Christmas" movie (or Hogmanny) and we watch it every year. Strangely, I haven't posted about Hogfather, but I have posted about this movie! Funny, I didn't remember that we'd seen it at all. Well, it was fifteen years ago. This post doesn't really add much, but I've already written it so I'll let it stand.
