I just love how Frank Lloyd Wrights 'Ennis House', finished in 1924, gets introduced as "built a century ago" in House On Haunted Hill from 1959.
The building used to be in bad conditions the past years and is going to get restored. More here: http://en.wikipedia.org/wiki/Ennis_House
This is kind of a fast-forward-film, btw...in horror terms. Not now-creepy at all, of course. Though you understand a lot more about where modernish thrillers/horror films start.
