In this post, I showed examples from different sources that I believe were used by the creators of Disney’s Haunted Mansion as influences.
This E.C. comic from the 1950s is one source that I believe at least partly inspired the seance room scene with Madame Leota.
But I’ve found another possible influence that, because it was a film, I believe may even be more of an influence on Disney’s designers. I wouldn’t have known anything about it if Svengoolie hadn’t broadcast on MeTV a Rondo Hatton movie from the 1940s…a movie in the Inner Sanctum series of horror/thriller films, each of which was introduced by…
Madame Leota’s forefather? You make the call…
