Seymour says it was an "amazing experience" shooting in New Orleans and Jamaica. "I stayed in fancy hotels. I had the most amazing costumes," but she most enjoyed spending time with Geoffrey Holder, who starred in the film as the villainous Baron Samedi. "He was a choreographer, and he was rehearsing all the dances for the voodoo sequences," says Seymour. "So whenever I wasn't on one set, I ran over to the other [stage] and joined in the dance. I always felt much more comfortable dancing than I did acting, so it was a perfect combination for me. I'd sort of run off. They'd say, 'Where's Jane?' And someone would say, 'Oh, she's off rehearsing with the voodoo guys.'"
In fact, her downtime with Holder resulted in an iconic image associated with the film. "One day, we went down to the beach in our costumes and we did a sort of dance kind of improvisation on the beach. Someone took photographs of it, and that ended up on all the posters," she says (image below). "It had nothing to do with the movie at all. It was just Geoffrey and I dancing in our costumes."
