Han and Leia
Han and Leia never said "I do" in the "Star Wars" films (they just smooched a few times and acknowledged their feelings), but they had a wedding of intergalactic proportions in the novel "The Courtship of Princess Leia" by Dave Wolverton.
Even though Leia wasn't sporting her famous golden bikini from "Return of the Jedi," Wolverton still gave the space-faring swashbucklers a ceremony both fanboys and romantics could enjoy. The nuptials took place on the city-planet of Coruscant in the White Room of the Alderaanian consulate, a large, softly lit space with a high-vaulted ceiling and small altar over which the scoundrel and princess said their vows.
The 1,000-strong crowd included almost all the characters you'd expect. Luke, R2-D2 and Chewbacca (who was groomed within an inch of his life) attended, of course. C-3PO was in the building, but the unlucky droid spent the ceremony locked in an empty room. He wasn't dismembered, however, so it was a good day for him, too.
