Disney nixed the ghost of Rasputin for the Haunted Mansion

One of the fundamental decisions that confronted the Imagineers who put together the Haunted Mansion was choosing which ghosts and ghoulies to put before the public. It was like writing a recipe. How much should the Mansion rely-if at all-on cinematic ghosts? or Halloween decoration ghosts? [...] [Disney Imagineer Marc Davis] also planned to use Rasputin. Believe it or not, Walt nixed this one himself, not because it was so weird but because he feared that relatives of Rasputin might still be alive (which was true) and might want to sue them! Marc recycled some of his unused Rasputin portrait into one of the Sinister 11, the one sometimes referred to as "the ogre."
