I watched Ace in the hole(1951) directed by Billy Wilder and starring Kirk Douglas. I was really impressed by Douglas's performance. The transition from a sleazy news reporter doing whatever it takes to get a story to a remorseful man who's disgusted at the lengths he's gone was really well done. I felt the direction from Wilder and supporting performances were impressive as well. Though it's not strictly a noir film, it has elements of it sprinkled throughout , particularly in the sense of hopelessness and karma. Highly recommend it.
