Looking at that trailer, you'd be mistaken in thinking it's a Christopher Nolan film. But then the title card "from the co-creator of Westworld" pops out and you think it's his brother Johnathan Nolan. But no, the movie is actually directed by Lisa Joy, with Johnathan as a producer.
This movie would have looked interesting to me if it didn't copy so much from Nolan's Inception. Yeah, they're dealing memories here rather than dreams, but it feels like it's treading on familiar ground. We'll have to see if it comes out good and with something original to say.
