"She's so delightful," Julianne Moore, who plays her demented mother in the horror flick, recently gushed to E! News.
"I mean, she was 15 when we shot this and she's very professional, really talented, very engaging and wants to do well and great work," Moore continued. "I love her. I loved being with her. She was a great partner and I wanted to make sure that she felt safe with me and that anything could happen and that I was not going to hurt her and that we could kind of explore this relationship together."
