Watch the Official Trailer for New Haunted House Movie WINCHESTER, Starring Helen Mirren

Do you believe in ghosts? Sarah Winchester sure did, and her resolve to protect her family from sinister spirits is the main focus of the new horror film Winchester. Starring Helen Mirren, Jason Clarke, and Sarah Snook, Winchester will haunt theaters this February, and CBS Films has opened the door to the official trailer for those who dare to step through its threshold.

You can watch the new trailer below, and in case you missed it, read our own Heather Wixson's impressions from her visit to the real-life Winchester Mystery House.

Synopsis: "Inspired by true events. On an isolated stretch of land 50 miles outside of San Francisco sits the most haunted house in the world. Built by Sarah Winchester, (Academy Award®-winner Helen 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 (Jason 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..."

Directed by The Spierig Brothers, Winchester stars Helen Mirren, Jason Clarke, Sarah Snook, Angus Sampson, and Finn Scicluna-O'Prey. Lionsgate and CBS Films will release the supernatural thriller in theaters on February 2nd, 2018.
