Willow is one of George Lucas' lesser know works.
Willow is a little gnome thing who wants to be a great magician and battle dark lords but he has a lack of confidence, so naturally it turns out that he is destined to to save the world from a female version of Emperor Palpatine with cooler powers. He defeats her using slight of hand tricks.
Other major characters include Mad Martigan (Han Solo as a red bearded swordsman) and the Empresses daughter who has a sword with another sword that springs out to form a double sword. She betrays her mother to be with Martigan, making her an amalgam of Princess Leia and Darth Maul.
The movie is actually not horrible, but the only scene that approaches greatness is when Willow uses his awesomely powerful wand (which he can't really control yet, of course) to transform a charging troll into a gigantic fire-breathing dragon thing, which easily out paces the empress and her dark knight (who has a mask that looks like a skull and killed Martigan's father or something like that) as the most visually impressive villian, and the most climactic fight scene.
Obi-Wan is also a chick, but she spends most of the movie polymorphed into a talking goat that shouts "Willow! Use the wand!"
I am not making this up.
