In Vincent Price's version of "The Cast of Amontillado," not only are pieces missing from Poe's original story, the conclusion is also much different than Poe's version.
At the end of the video, the climax of the story is the end of the story: Montresor informs his audience that he has walled up Fortunato—buried him alive. That is the video's end, and with the music and the close-up of Vincent Price's face, along with the lighting, it has an impact.
However, I find Poe's version is creepier, giving us the full effect of how insane Montresor is. As Poe tells it, the shackling of Fortunato, the conversation, the merciless verbal torment at the hands of Montresor, as well as Fortunato's hysterical laughter, abrupt silence and then only the sound of the bells on his hat have a much greater impact on the reader.
True, sound and visuals often are very effective in telling a story, but Poe always (and only) could depend on the imagination of the reader to fill in what might have been missing in his narrative...if there was anything missing at all. Poe was a masterful storyteller.
Poe captured the essence of Montresor's madness and his sociopathic nature: Montresor feeling no remorse says, "May he rest in peace" (a macabre statement in that he could not wait to bring about the other man's "immolation"), and then he casually observes that the body had not been disturbed in over fifty years. It is eerie to note that even as it has been at least fifty years since the death of Fortunato, Montresor has taken great relish in reliving the experience.
