Review of The Tell-Tale Heart

I saw this short back in 1953 when I was just a kid. Had nightmares about it for a long time after. I haven't seen it since and have always wondered why. Was there some reason it was taken out of circulation? The mood and atmosphere with the juxtaposition of UPA animation (cartoons in those days-mostly associated with Mr.Magoo and Gerald McBoing Boing.) and thriller-style mood piece was groundbreaking. Since then I've been a fan of Poe's and especially that story. If anyone knows where it is or how I might see it again I'd love to know where I could get a copy. Anyone? Pleeeez? Is there other thriller-type animation out there? (No I'm not talking about Scooby Doo!)
