"I don’t know if watching your own work is a good or bad thing. I don’t know how much I learn from it. Each individual circumstance holds its own world of singularities and peculiarities. But among that, you can go: “Oh yeah, I remember that was what I tried to do.” Sometimes it doesn’t fit with the cast or the energy of the scene or the beat of another character. But to sit down in the audience and go: “Oh my God, I think that was what I intended”, was great."
