Ordinary Londoners - No 17 in the Series (Eden Lake)

"I'm not a politician or a sociologist - I want to tell a story. The horror is within." The words of James Watkins, Londoner, writer and director of Eden Lake, a new film for which I attended a screening, I took the portrait during a Q&A session afterwards.

The film is not comfortable; if you have any quantity of squeam, you may be better avoiding it. But I think it is one of the best British films made over recent years for many reasons, not least because it makes you think. Written before the recent increase in newsworthy knife and gun crime it is now ferociously topical and confronts violence head on - just where you hope you will never be. From its start it suckers you into thinking you'll be watching an ordinary schlock horror film but there are masterful little touches that turn it onto a different track and create moral ambiguity that involves you in the plot. Think "Deliverance for the 21st Century, made in England" and you're pretty much there.

It's released on the 12th September, certificate 18. I'll leave you with another quote: "If you can't be thought provoking in a horror movie, when can you be?"
