So they did renovations on the house and turned it into a museum and they're giving tours and stuff. I guess a lot of it wasn't actually filmed in that house though, and they had to totally reconstuct some of it to match how it looked in the film, like the staircase.
I think it's cool that they revived it like this.
I'm gonna go see it sometime soon, I live about twenty minutes away (my grandma's house is a few houses down actually--you can see it in the movie.)
