"Ansel is whip-smart and uber-charismatic and everything I dreamed for Augustus Waters," John Green tells Entertainment Weekly. "I am by nature a cautious pessimist, but I'll just say it: Now that we have Shailene and Ansel, I am completely, unreservedly psyched about this movie."
Director Josh Boone adds, "Ansel Elgort is the epitome of the boy John Green brought to life so vividly in his novel and he truly embodies the character traits we admire so much about Gus. His humor, sensitivity, honesty and confidence floored us. Watching him with Shailene was like seeing the film for the first time.
