Jon Stewart on portrayal of torture in Rosewater

Fareed speaks with Jon Stewart about his new movie 'Rosewater'. Watch the full interview this Sunday at 10 a.m. and 1 p.m. ET on CNN.

Did you think about how you were going to make this movie work despite the fact that everybody knows how it ended? To me, what was so effective was the torture felt very scary even though I kind of knew that he was going to be all right at the end.

Right. I think that's something that is the difficulty within a story like this...thank goodness we knew the ending.

So it was a question of creating dynamics within that that were hopefully complex enough that could give people some insight into it, but also, again, a more visceral experience, that feeling of being on the edge of your seat and that discomfort, only to have that alleviated in sort of one large cathartic moment. And to break that through and watching not just that he would get out, but how he regained his humanity and how he sustained himself.

There are so many interesting lessons to be gained from how Maziar was able to retain his humanity given the conditions that he was under.
