I've been impressed with Joseph's other recent work like "hit record". For me personally I can't think of anyone better for the role.

Also maybe relevant is his opinion not an opinion after meeting Snowden for research on the role:

> "Now, as he would say, it’s not for him to say whether it was right or wrong. That’s really for people to decide on their own, and I would encourage anybody to decide that on their own. I don’t want to be the actor guy who’s like, ‘You should listen to me! What he did was right!’ I don’t think that’s my place. Even though that is what I believe – that what he did was right.” [1]
