10 Horror Reveals Nobody Was Ready For

10. The Switcheroo - The Skeleton Key

For the most part, The Skeleton Key is a movie that seems to play it safe, rolling along at a steady pace and exploring a few elements of voodoo - or hoodoo, as it's referred to here.

What The Skeleton Key does have going for it, though, is the sort of reveal that can make a film be forever remembered.

By the time all is said and done with this 2005 picture, Kate Hudson's Caroline has been body-switched with old and frail Violet Deveraux. That was all done by an ancient ritual called Conjure of Sacrifice, with the form of Violet having actually been housing the spirit of hoodoo expert Mama Cecile.

The painstaking irony here, of course, is that the only way that Mama Cecile was able to take control of Caroline's body was to wait for Hudson's character to start believing in hoodoo. As Caroline begins to think that John Hurt's Ben is being affected by hoodoo, her research into this leads to her becoming a believer in this dark art - and thus, her own demise is sealed, as this now makes her susceptible to the powers and spells of hoodoo.

The gut punch of The Skeleton Key, is that you now realise that Caroline has to spend the rest of her days as a partly-paralysed mute trapped in someone else's body, unable to tell the world or warn the next potential victims of Mama Cecile and her long-time partner Papa Justify.
