Clarke, who wrote the script and stars as everyman-turned-hero Charlie, spoke to Digital Spy about his inspiration for the script, and the challenges of making science fiction in Britain.
He explained that the kernel of the script came to him after spending a lot of time inside storage lockers.
"[I just started] thinking about how freaky they were, because they were just corridors of padlocked doors that didn't lead anywhere, you didn't know what was behind the doors," he said.
"And I thought this would be creepy if you were hunted by something in there."
Clarke went on to discuss the relative lack of science fiction being made in Britain.
"I think in films the writers aren't there," he mused. "People aren't necessarily wanting to do that because we don't have the budgets to do it... to have massive spaceships and aliens and all that kind of thing. But as technology gets better it enables you to do things."
