As the woman turns the lights off and on, the figure soon appears to be closer. When the woman is in her bedroom and the light flickers, she hides but when she turns around, she sees the face and hands of a figure with pupil-less eyes and open mouth. The figure turns off the light on the night stand. In feature film In the 2016 film, Diana is a mysterious figure that attacks people only in the dark. It is revealed she was a patient at a mental hospital who had Xeroderma pigmentosum, a serious skin condition that prevented her from being exposed to any light. During her time there, she befriends Sophie, who was there for treatment for her depression. They take a picture together outside where she is covered in shadow by an umbrella. Doctors began performing experiments on Diana, but finally killed her by overexposing her to intense light ( ~ 2000 watts ) where her body was reduced to ashes. Diana then turns into a demonic, malevolent creature that can act only in the darkness. The creature latches onto Sophie, and kills anyone to tries to help or be with her. She interferes with Sophie 's intentions of trying to get better, and frightens Sophie 's daughter Rebecca by taking her drawing of her family and inserting herself into it as a stick figure while rubbing out her father, that Rebecca moves out of the house. Some years later, she appears at Sophie 's second husband 's work place and kills him. She haunts Sophie 's second child, Martin, that he is unable to get sleep anymore. When Martin is at Rebecca 's place, she goes there and haunts them, scratching onto the floor her name and a stick figure resembling Rebecca 's old drawing. She returns to the house where she continues to influence Sophie, who suggests a stay - in movie night with Martin, including Diana as `` the three of us ''. When Sophie tries to take her pills, Diana knocks them aside. Diana tries to pull Martin under the bed, but Rebecca stops her. She locks Rebecca and Martin in the basement, and attacks Rebecca 's boyfriend Bret, who flees to get help. She ignores Sophie 's pleas to not hurt her kids, and continues to attack in the dark, killing two police officers. However, as Diana is about to kill Rebecca, Sophie arrives and states that Diana only exists because Sophie has allowed her to exist. Sophie then shoots herself in the head, and Diana disappears. Sequel A sequel titled Lights Out 2 has been planned. Development Conception David said that his goal was to keep Diana 's appearance in the film as a silhouette. When asked about how challenging it was to keep Diana in the dark he said `` Very challenging because I did n't want to cheat. I had to storyboard all of it just to make sure that she was truly a silhouette. At first I was working with a storyboard artist. He would draw her with a rim light on her and I was like, `` No, we ca n't shoot it like that because that 's cheating. '' So I had to do my own storyboards and really figure out how we could always keep her as a true silhouette. When she grabs Bret, I had to think about, `` If he uses his flashlight like this to bang on the handle, if she grabs him when he 's up here, then the flashlight is pointed backwards creating a silhouette so that she can actually grab him. '' It was really hard to figure out exactly how to get her on film. '' Diana was originally suppose to be more of a demonic presence but James Wan suggested that she have a human background so she could have a relationship to Sophie and add to the connection to the family. Casting In an interview, when asked about the casting of Diana, David said ``... I figured she would be pretty still but once I met Alicia, we met Alicia just to have her as a stunt person for whoever would play Diana. But when I met Alicia and she showed me what she could do, because she 's a dancer and she has full control over her body, it was like, ' Oh, this is really awesome. So let 's have Alicia play Diana the whole time and we can really turn her into this ferocious, animalistic creature almost.
