I highly recommend "director chasing" meaning, if you like a movie by a director, check out their other stuff. I really liked "Ex Machina" dir by Alex Garland which led me to "Annihilation" (both fit your criteria). I loved "Se7en" dir by David Fincher so I checked out all his other movies, my favorites being his version of "The Girl With the Dragon Tattoo" and "The Game" (social network and fight club also classics, can't really go wrong with him). I LOVED "Arrival" dir by Denis Villeneuve which led me to all his terrific movies. You mentioned "Interstellar" I would recommend Nolan's 2nd movie "Memento", big ol twist in that one. Another that would fit the bill is "Shutter Island" dir by the legend himself Martin Scorsese. Could find a number of great films there too. Hope this helps.

Me and my girlfriend watch a lot of thrillers because it's like the only thing we both like, lol.

• Prisoners (So good, we watched it twice and we never do that. It's an incredible movie.)

• Gerald's Game (includes the most horrific scene I've ever seen in a movie)

• Get Out (The Jordan Peele movie that took everyone by surprise by how good it was)

• Nightcrawler (An absolutely crazy thriller)

• Gone Girl (I second this recommendation.)

These 5 are among the best of the best, in my opinion.
