The Haunting (1963)
The mansion in Clue, and both The Haunting films are called "Hill House". The Haunting films are based on the book "The Haunting of Hill House" which is about a group of people being invited to a creepy mansion, which is the same set up as "Clue" as well.
Similar premise and plot: a group of amateur paranormal investigators carry out an initially sceptical study of a local legend, but apparently (though ambiguously) fall victim to it. The nature of the antagonist is never made clear, it is only manifested through enigmatic signs (mainly sounds), and the possibility is left open that it was nothing more than a combination of paranoia in some group members and one of them losing his / her mind (although equally the possibility of the insane member having been possessed by the "entity" is left open).
