White Zombie (1932)

Murder Legendre is the menacingly named zombie master of Haiti. Charles Beaumont goes to him when he needs help for a twisted plan. Spurned in marriage by Madeline Short, Beaumont has decided on a simple solution: kill Short and bring her back as a zombie. Then he can be with her forever. The only problem comes when Legendre keeps the fetching girl for himself -- and her new husband comes to Madeline's rescue.
