12 Movie Openings That Totally Trolled Audiences

12. The Descent

Hellboy director Neil Marshall’s 2005 horror masterpiece The Descent is easily the Dog Soldiers director's best loved film, a claustrophobic nightmare which sees a set of women besieged by cannibalistic monsters when they venture far too deep into a remote cave system and become stuck.

Which makes it surprising that this bleak, unrelentingly grim and gruesome movie opens with a happy family picking their beloved mom up from a fun white-river rafting girls trip.

Then there's a little awkwardness on the ride home... and then out of nowhere dad and daughter alike are skewered by a passing truck’s cargo.

Right, there it is, so the unremittingly dark two hour nightmare begins. Start on a gory shock and work your way right back up to them, as the experts always say. Good luck ever sleeping again, viewers!
