The other night I got the chance to see the 1977 Japanese film ハウス (Hausu),
alias House.

I’m not sure what I can tell you about it of import that the insane trailer doesn’t —
save to verify that while House does have at least the framework of a story it lives up to the trailer’s wildly abrupt shifts in scene and tone. Even if you don’t think you’ll ever watch the film, I urge you to click through the link for its distillation of sublime weirdness into 1¾ minutes.
