Has "Live and Let Die" supernatural elements?

Maybe it is only my interpretation of the movie but I personally think it is the only Bond movie with supernatural elements/characters. I am talking about Baron Samedi especially. Is this character truly supernatural/inmortal or it is just the way I perceived the movie?

I love "Live and Let Die" but I don’t like the supposed supernatural element because I prefer the "realism" of the franchise (yes, I know it is really hard to talk about realism in the Bond movies,especially in the Roger Moore movies with bizarre characters like Jaws but at least the rest of the movies didn’t have these supernatural elements)
