Watch Insidious: The Last Key

This fourth instalment in the smash-hit supernatural horror series - the sequel to the first prequel for those keeping score - sees Lin Shaye return as brilliant parapsychologist Elise Rainier. And this time, as the saying goes, it's personal. When a call comes in about a potential haunting the address is revealed to be none other than Elise's own childhood home, which - as the 50s-set prologue reveals - was originally built next to a prison's death row facility and has a suitably disturbing past. Writer Leigh Whannell (who directed the previous entry and co-created the Saw franchise) appears as ghost-hunting sidekick Specs.
