Hostel director Eli Roth has chosen the next film project that he's going to direct. It's called Knock Knock and it will come from a screenplay that he co-wrote with Nicolas Lopez and Guillermo Amoedo, who also worked on the film Aftershock which Roth produced.
According to The Wrap, the story follows two young girls who show up unexpectedly at the home of a married man where they seduce him and wreak havoc on his perfect life.
It definitely sounds like a film project that Roth would take on. He enjoys torturing people in the movies he makes. The filmmaker recently finished his cannibalistic horror movie The Green Inferno, and there was a six year gap that and the last movie he directed Hostel II. I imagine he doesn't want to take a long of a break again in-between films.
