The Long Halloween and Dark Victory by Jeph Loeb and Tim Sale are really good and very similar to the movies, as is Batman: Year One by Frank Miller. The Killing Joke by Alan Moore is a good Joker story, similar to the Joker graphic novel. Also, they're a littel hokey, but I enjoy the Batman: Vampire stories and Batman: Haunted Gotham, mostly because I love Kelley Jones' art style. Hush is definitley good too!
