If you like scary movies, I’d recommend Insidious, made by Australian duo James Wan and Leigh Whannell. I’ve just posted its tech details, and noticed the front cover of the US version of the Blu-ray. This notes in promotional terms that it is the ‘most terrifying film since The Exorcist‘, and that it’s from the ‘Makers of Paranormal Activity‘ (most of the producers are the same for both).
Then it adds ‘and Director James Wan and Writer Leigh Whannell’.
That’s a bit strange because it doesn’t attribute to them any credits in the conventional way. Perhaps it’s because the most famous credit for the pair is the Saw franchise.
