Five all-American college students (including Chris Hemsworth) head off for a weekend getaway at an isolated cabin, but their hi-jinks quickly turn to terror when they unwittingly unleash sinister forces.

So far, so familiar, but writer-directors Joss Whedon and Drew Goddard aren’t churning out just another haunted-house or slasher movie. Instead, they’ve come up with a mischievous, mind-bending chiller that turns the horror genre inside out – and it may all have something to do with a group of scientists in white coats.

A giddily funny, gulpingly scary, enormously entertaining thrill ride.
