To me it is harder to play a real person, but when you do it and you feel good about it and the person feels good about it, I think that's doubly rewarding. So the challenge is greater, the risk is greater, but the reward is greater as well.
If you're playing a fictional character, you can create a character, you can sort of take certain liberties. And when you're playing a real person who's actually standing there watching you, you know, it's - you do feel a weight. You know, you feel an obligation to not only be - to give the best performance that you can, but to make sure that you represent this person.
