Legally, they are totally covered

The disclaimer at the start of the film I Walked With A Zombie (a zombie film with a similar plot to Jane Eyre) states: “The characters in this photoplay are fictional. Any similarity to actual persons, living, dead or possessed, is purely coincidental.”

Oooooh! Scary stuff, kids! Let’s see if the film lives up to the opening credits.

(later) It was actually a solid spooky West Indian set horror film. There was commentary by two British film guys (sorry, guys, I don’t have the video box in front of me or I’d say who you are) who did a good job pointing out interesting things about the movie until it was time for me to head to bed. The most interesting part was the long and storied life of the calypso song that first reveals the dark secret of the island’s most powerful family, “Shame and Scandal”. Mentioned in the movie commentary but not the Wikipedia article (yet) is that it was often used as the tune for songs commenting on political shame and scandal. Pretty cool!
