Following the posters revealed a couple of weeks ago, here's the full-blown trailer for Sinister. The supernatural thriller stars Ethan Hawke, is produced by Jonathan Blum (Paranormal Activity, Insidious) and directed by Scott Derrickson.

The film has Hawke as a hack writer who moves into a house that was the site of an entire family's gruesome murder. Oh, and he brings his family with him. He then discovers a box of films of other murders stowed in his attic, and finds his ongoing investigation leading into hellish territory and his own family in some serious danger.

The trailer shows pretty much what you'd expect from that description, but it looks stylishly done, Hawke is always welcome, and we get some bonus entertainment from Vincent D'Onofrio as an internet expert on supernatural shenanigans.

What's new here is the monster: glimpsed on the posters and previously described as an entity called Mr Boogie, he's revealed here as a pagan deity called Bagul (that's buh-gool, not a bread product), who eats the souls of children and can get at you through pictures of himself. We think he's made up, with no real basis in any pagan pantheon, but he looks destined for a bright future as a Hallowe'en costume and a Todd McFarlane action figure.

Derrickson cut his teeth on franchise sequels like Hellraiser: Inferno and Urban Legends: Final Cut, before branching out with The Exorcism Of Emily Rose and the remake of The Day The Earth Stood Still. He also contributed a screenplay draft to Atom Egoyan's The Devil's Knot.

Sinister has already played a few festivals and picked up some positive vibes, but still has some distance to creep before its proper US release date on October 5. We don't seem to have one for the UK so far, but while we're waiting, the official website is gradually coming together.
