Oscar sings this song to impress club owner (F Murray Abraham) in the movie What's Inside Llewyn Davis. And he is very impressed (in real life)

N: You play a very pivotal role in the film, being the man Llewyn needs to impress to get his career going, but in the movie while he’s playing you have to remain as motionless and tell-free as possible. How was that for you to do? He’s obviously doing a great job of playing and yet you have to show no emotion at all.

FMA: Yeah, it was tough because it’s a very touching song. The first time he played it, I almost started to weep, which is not the right thing. He delivered every time, one take each time that long, moving end-shot. It was wonderful to see. I think he did it four times. It tore his heart out every time. I don’t know if you know that he played it live. He was playing and singing. It’s not prerecorded at all.

N: That’s amazing.

FMA: Isn’t it?
