In successful relationships, there are plenty of reasons why we find our partners attractive. So it should come as no surprise that Jennifer Lawrence’s acting talent impressed Darren Aronofsky, who worked with the actress on Mother!, a thriller that’ll be in theaters soon. Lawrence and Aronofsky started up a relationship after the film wrapped.

Aronofsky opened up about his admiration in an interview with Vulture — but first, he discussed the movie in question. Aronofsky is responsible for some of the most chilling films in the past few decades, and while we don’t know too much about Mother! based on the trailers that made the rounds, we can tell it’ll be like nothing else out there.

Aronofsky also noted that there were many things Lawrence brought to the movie all by herself.

For an actor, that’s definitely a high compliment. It shows that Lawrence has a ton of range, and can take bits of a role and turn them into something completely wonderful and believable.

In fact, Lawrence got so into the role that she apparently broke a rib during one of the more intense scenes. Ouch. Sometimes art hurts.

Mother! will be in theaters on September 15th. We can’t wait to check it out.
