I just came across this earlier this morning.  This short, animated film is from 1953 and it features James Mason reading a story from America’s first master of suspense, Edgar Allan Poe!

Here, for your listening and visual enjoyment, is The Tell Tale Heart!  Along with featuring the voice of James Mason, the film was directed by Ted Parmlee.  It was the first animated film to ever be given an X rating by the British Film Board of Censors.
