Lionsgate and CBS Films’ Winchester: The House That Ghosts Built stars Academy Award winner Helen Mirren as firearm heiress Sarah Winchester who spent decades using her fortune to expand upon her home, and no one is quite sure why. The most common belief? She was cursed by spirits who demanded she never stop building.

Directed by Michael and Peter Spierig (Daybreakers, Predestination, Jigsaw), we were able to get our hands on a few clips, all of which help construct the story behind Winchester. This clip is probably the most relevant, as Sarah Winchester explains why she’s been building all of the rooms. The footage all the way at the bottom of this story also tours the labyrinth within, as well as gives us one of our very first scares. There’s also a great featurette that dissects the film based on the real-life haunted house.

In the film, “On an isolated stretch of land 50 miles outside of San Francisco sits the most haunted house in the world. Built by Sarah Winchester, (Mirren) heiress to the Winchester fortune, it is a house that knows no end. Constructed in an incessant twenty-four hour a day, seven day a week mania for decades, it stands seven stories tall and contains hundreds of rooms. To the outsider, it looks like a monstrous monument to a disturbed woman’s madness. But Sarah is not building for herself, for her niece (Sarah Snook) or for the brilliant Doctor Eric Price (Clarke) whom she has summoned to the house. She is building a prison, an asylum for hundreds of vengeful ghosts, and the most terrifying among them have a score to settle with the Winchesters…”

In theaters February 2, 2018, Winchester also stars Jason Clarke, Sarah Snook, and Angus Sampson.
