Siegel (who, fun fact, is married to Haunting‘s creator Mike Flanagan) has actually been in a lot of other horror projects like Oculus, Ouija: Origin of Evil, and Gerald’s Game (which also starred her Haunting “mom” Carla Gugino!). Grace, meanwhile, already has a lot of credits under her belt — recently, she played the younger Tonya Harding in I, Tonya and will star as the young Carol Danvers in next year’s Captain Marvel.
