Ever since the last "Lord of the Rings" movie came out, people everywhere have been looking for something to nerd out to. The ingredients are few, but difficult to find: Big and expansive fantasy worlds, solid characters, and an epic story, preferably one that takes two or three movies to tell effectively (plus bunches of novels, comic books, and video games to flesh things out). The "swords and sorcery" element isn't a must, but it is preferable. Here are four movies that meet a decent number of these requirements.

"Star Wars" Peter Jackson, the director of the "Lord of the Rings" movies, is a big "Star Wars" fan, so it makes sense that "Star Wars" might have some of that nerd-trilogy action you're looking for. In fact, there are two whole trilogies of sword-vs-monster action for you to chew on - the only difference is the swords are made out of lasers and the monsters are voiced by classically trained British actors.

"The Wizard of Oz" It's known primarily as a splashy Hollywood musical, but this is also one of the best fantasy-adventure films ever made. The whole last act doesn't even have any songs, and it's based on a popular series of novels, just like "Lord of the Rings." Even the plots are similar: A brave young person has to go on an adventure with a group of friends to a strange world in order to, uh, do something. It's tomato, tomahto!

"Zardoz" Sometimes you just want to watch something that's so f*cking weird it makes "The Lord of the Rings" look like "Scenes from a Marriage." If that describes you, consider "Zardoz," starring Sean Connery in one of his first post-Bond roles. The story has to do with a mystical post-Apocalyptic land, giant talking stone heads, and Sean Connery in the most ridiculous movie costume ever worn. Nerding out is pretty much the only acceptable response to this one, since anything else would result in complete insanity.

The "Tarzan" Movies They might not have the tight continuity of "The Lord of the Rings," but there's plenty of action and adventure in this other series based on fantasy novels. And Tarzan himself is pretty badass, certainly holding his own against Viggo Mortensen and the guy who played the dwarf with the beard. Maybe you could hammer out some fan fiction about Tarzan hanging out with Frodo and his pals, although that might be too nerdy even for this.
