Lois, the woman in the bottom right is Shelley Duvall, who played Wendy Torrance in The Shining. She apparently went through large amounts of mental and emotional trauma and torment when filming this movie. Stanley Kubrick did this on purpose to make her fear and dread more realistic in the movie. She was isolated, Kubrick was "unusually cruel and abusive" to her, and most famously, the baseball bat scene was reshot so many times it broke the world record for most retakes of one scene. It was reshot that many times specifically to make Shelleys acting and reaction more upsetting and unnerving, all of this was at the expense of Shelley's long term mental health.
