Back in 2013, director Ilya Naishuller released a short film with a naughty title, and it took the internet by storm.

The film, which was filmed entirely in first person and cameo'd Hollywood star Sharlto Copley, was viewed almost thirty million times on YouTube alone. You can watch that very violent clip right here.

Off the back of that project, Naishuller was given the opportunity to work on a much bigger project.

Using the same first-person perspective, and bringing along Sharlto Copley for the ride, the new feature length movie Hardcore is getting it's world premiered at the Toronto International Film Festival last night.

To celebrate the premiere, the first official trailer for the movie has been released, and anyone who suffers from vertigo - or a weak stomach in the face of strong violence - may wish to look away now.
