"Haunted Theater" ?

In the Michael Feir interview in the Get Lamp interviews on archive.org, he often refers to a game called “Haunted Theater”. I can’t find anything about this game in the ifwiki or ifdb. Does anyone know what game he is referring to? Perhaps a different title?

You may be thinking of “Theatre”, which is a Lovecraft-style horror game. See ifwiki.org/index.php/Theatre
