Brothers will write and direct Hammer’s spookfest… UK-based Hammer Films has announced that a supernatural thriller based on the Winchester Mystery House is in the works with Aussie filmmakers Michael and Peter Spierig (‘Predestination,’ ‘Daybreakers,’ ‘Undead’) attached to write and direct. The Winchester Mystery House has a startling history and attracts hundreds of thousands of tourists annually. Popular belief holds that Sarah Winchester, heiress to the Winchester Rifle fortune, was convinced she was haunted by the spirits of those killed by “the gun that won the west.” Following a Medium’s advice, Sarah built a massive house in Northern California to appease the spirits. For the next 38 years, she never stopped building believing that if she continued, she would live forever, and if she stopped, she would die. Known as the “house built for the spirits,” there have been many inexplicable ghost sightings and to this day, visitors share their terrifying stories of having been in the presence of these departed souls who continue to roam the grounds of the intricate and enigmatic house. “We can’t wait to see what the Spierig brothers unearth as they delve in to the mysteries of Sarah Winchester and her infamous haunted house,” said Tobin Armbrust of Hammer Films. “As the first feature film ever shot inside the Winchester Mystery House, we are excited to have these fantastic filmmakers bring their unique vision to the table.” Production on the spookfest will be overseen by Armbrust, and Shira Rockowitz, Director of Development and Production. Brett Tomberlin and Antonia Lianos will produce for Imagination Design Works, Inc along with Andrew Trapani and Brian Gilbert for Nine/8 Entertainment.
