What's fun about this rumored house is there's more than one version of "The Fly", yet no matter which one Legacy is referencing, it's no less exciting.
Since you have the original 1958 version, which I feel is more in line with Slaughter Sinema's humor since it's a classic B-movie. (The same can be said for its two sequels.) But then you have the 1986 remake, which goes into full-on body horror.
For me, either choice is totally fine. And this could very well rocket up my hype list very quickly once it's announced!
