Vera Farmiga in The Conjuring
Prior to signing on for The Conjuring, Vera Farmiga knew little of her character's past. Ed and Lorraine Warren were real-life paranormal investigators who were associated with high-profile hauntings. On the night Farmiga began researching Warren's work, she ended a phone call with director James Wan and opened her laptop only to be met with "three digital claw marks, from the upper right diagonal to the lower left."
