10 Movie Posters That Spoiled EVERYTHING

10. The Ritual - The Cabin In The Woods

Most of the marketing for The Cabin in the Woods nicely played coy about the precise nature of its seemingly tropey horror movie setup. The trailer did of course suggest a sci-fi twist, but still kept things vague enough to be interesting.

But the poster for the film's Japanese release dropped any and all pretense of preserving the big secret, by blatantly showing the underground facility which contains the various cube-like prisons containing the monsters unleashed at the end of the film.

The poster makes it painfully clear that The Cabin in the Woods isn't just an Evil Dead knock-off - it shamelessly reveals the big sci-fi conceit that isn't fully unfurled until much late in the story.

Sure, it doesn't quite go the whole hog and write, "It's part of a world-saving ritual!" in neon lights, but gives more than enough context for most people who see the poster to start figuring out what's going on.
