Just in time for Halloween weekend, we have the first teaser trailer — actually a pretty extended teaser at that — for the Winchester Mystery House movie that you've been hearing about all year, now set for a winter premiere. Winchester: The House That Ghosts Built, starring Helen Mirren and Jason Clarke, centers on the true story of Sarah Winchester, the widow and heir to the Winchester firearms fortune, who as the legend goes, built her sprawling, creepy, idiosyncratic manse in San Jose in an effort to outrun and confuse the ghosts she believed were haunting her — ghosts of those who were killed by Winchester guns.

Up until now, all we've seen of the film is the imposing portrait of Mirren, decked in black and sitting in a carriage. Now we have a glimpse into the vision of filmmakers Michael and Peter Spierig (Daybreakers, Saw: Legacy), who have clearly taken liberties with real-life events to tell the story of Winchester, who was being treated by a San Francisco psychiatrist, played by Clarke, apparently hired by other Winchester heirs in an effort to declare Sarah mentally unfit to manage her own funds.

The trailer has a few of its own ghostly, jump-in-your-seat moments, and it just might be a winner! As Michael Spierig told People Magazine earlier this year, "I think everyone will be pretty scared."

And, clearly, never has the Winchester Mystery House looked so scary — though as we heard when they were shooting earlier this year, most of the interiors were done on a studio set in Australia, to save money.

Winchester: The House That Ghosts Built hits theaters February 2.
