The title pretty much says it. If you could get a Pixar/Dreamworks/Blur/etc. team to do ahigh quality animated movie of a book, or movies of a connected series, which would you pick, and why would you pick precisely that/those?
For me, it would be the Dirk Gently books, by Douglas Adams. The live TV show was adorable, but I wannt to see someone try to visualize the utterly bizarre stories in those books!
