I thought that the acting in this thriller was superb. All of the main actors were spot on and their interchanges believable. A good example of this was Kelly Reilly as Rowena Drake. I had to be reminded over and over again that this is the same Kelly Reilly who stars in the Paramount tv show Yellowstone. She was so convincing in her part, that she sure had me fooled. Isn't that what good acting should be. And some of the other performances were even better. But most thrilling about this thriller to me, was the Cinematograhy and Directing. Wow. One well thought out and spooky camera angle after another. And if you were watching for it, there are hundreds. So well Directed and Produced. Would make Speilburg envious. So go see it. Take notes. This film will be getting a lot of attention at movie awards time. Have fun.
