Tim Burton's Corpse Bride (2005)

An animated interpretation of a 19th Century Russian folktale, where a man mistakenly weds a corpse. Victor is travelling home through the woods when he jokingly puts a wedding ring meant for his fiance onto what he thinks is a stick, and recites his wedding vows. The stick turns out to be the rotting finger of a woman's corpse, who later comes back as a ghost and insists she is now legally Victor's bride.
