Daniel Day Lewis is an incredible actor and is known for completly immersing himself in a character on a set. I think he would be amazing to see on stage.
I adore Daniel Day Lewis, so I'd love to see him on stage. I also think Anne Hathaway is an amazing actress and singer so it would be great to see her create a character on a new musical.
I voted for Daniel Day-Lewis. He is so amazing that I think seeing him live would be amazing. I think Jennifer Lawrence would be a close second though.
