20 Things You Didn't Know About The Ring

20. The Cursed Video

The fictional 'cursed' (but definitely eerie) film was used in an early marketing campaign, with no mention of what it related to, which must have been baffling for those unfamiliar with the original movie. It was also sneakily inserted into DVD Easter egg menus and those who bought the thematically appropriate VHS got the full analogue experience.

Severed fingers, drowned horses, dripping blood, torn fingernails, menacing centipedes and writhing bodies - it's fully strange, yet all the images have a connection to the plot. If that one isn't enough, there's another two out there, the 'new' one used in the sequel and the Japanese original.

Extra credit for those sneaky enough to slip a copy into a charity shop drop.
