Most of the scenes involving Baron Samedi played by Geoffrey Holder from the film "Live and Let Die" (1973).
Baron Samedi is not just a character invented for the film, but is in fact a Voodoo Loa of death. The movie never makes clear whether this Baron Samedi is the Orisha himself or just a mortal who dresses in his persona, but it does lean towards this being the actual Loa due to his return from the dead at the end, just before the credits roll.
Geoffrey Holder is a world renowned dancer who contributed both as an actor and choreographer to "Live and Let Die." While his work in film is not extensive, he is known for his trademark laugh. Other memorable portrayals of Baron Samedi in cinema include those by Don Pedro Colley in "Sugar Hill" (1974), and more recently, though referred to by the name of Dr. Facilier, by Keith David in "The Princess and the Frog" (2009).
