20 Sundance Films That'll Hit Your Screens In 2015
4. Knock Knock
Eli Roth's 2013 cannibal film The Green Inferno never saw a wide release thanks to the collapse of his Spanish distribution company, but the Hostel director has carried on regardless.
Knock Knock stars Keanu Reeves - woah! - as a middle aged dad who falls prey to a couple of Spanish beauties who come calling one lonely evening, offering a good time...although, not necessarily for Keanu.
Already being called one of the most daring, nasty horror films of recent years.
