"One of the reasons we are in this business is to challenge ourselves,” Stewart explained to the NY Times. “And I really connected to Maziar’s story. It’s a personal story but one with universal appeal about what it means to be free.”
“One of the things that appealed to me about the story is that it does have lighter moments,” Stewart continued. “One of the things that kept Maziar alive was his ability to keep his sense of humor – to remember about joy and laughter – and see the absurdity of his situation.”
While Stewart is away shooting the film overseas this summer, "Daily Show" correspondent John Oliver will take over hosting duties for 12 weeks — eight of which the show will produce new episodes.
