"I find that with any good run on a show with good writers, they put something on paper and you put something back on film and that affects what they put on the paper the next time." Roberts quoted on AMC Blogs, Feb. 25, 2013
"I came up in the theater, and I learned pretty quickly that reading a review, whether it's good or bad, can strangely affect the next performances, because you're reacting to something that's been said about you. So I tend to avoid that stuff pretty studiously." Roberts quoted on IGN, March 29, 2013
