James Wan and Leigh Whannell's bonkers supernatural horror Insidious is this year's most profitable film so far, with box office currently at something like seventy times its budget. Inevitable then that talk should turn to Insidious 2, with producer Jason Blum telling Shock "I wouldn't say we're not considering it..."

Without wishing to get too spoilerific, the ending of the first film certainly leaves scope for more. Quite apart from the bizarre business with Patrick Wilson, we don't know what happened to young Ty Simpkins either. As with the best horror, it works to leave matters ambiguous, but should Wan and Whannell wish to continue, there are threads to pick up.

Happily though, there is some quality control at work. "There's no plan, no release date, nothing like that," says Blum. "I think James feels the same as Oren Peli, who was very sceptical about doing a sequel to Paranormal Activity until Michael Peri pitched an idea and it made sense. If Leigh comes up with a story that's inventive and that James feels is worth making - as opposed to 'let's make another movie and make money' - we would do it. And if Leigh doesn't, we won't."

Will studio pressure undermine those wise words? And would you like to see more of the spooky old lady and the weird demon puppet-maker with the fondness for Tiny Tim records?
