This vs. Argento's Black Cat

I never saw the Argento version so I can't speak to that.

This film is excellent though. If you like Poe, it's a must-see.

But this film deviates from the Poe story source material in that it melds the historical person of Poe with the narrator character in the Black Cat short story. So basically this version consists of about 50% bio-pic of Poe's life & 50% fantasy in which the real-life Poe lives inside of his Black Cat story.
