Ryan Gosling told The Hollywood Reporter:

There was one big scene where my character, Agent K, first meets up with Rick Deckard. I'm acting with Harrison Ford and I'm thinking don't screw this scene up. It's Harrison freaking Ford! I'm doing my big scene and I swear it looks as if Harrison is falling asleep. I say to Harrison "hey, my acting can't be that bad, can it?" and Harrison wakes up and says "it's nothing personal. I'm getting old so I fall asleep a lot. I do some of my best acting when I'm asleep."
