Man on Wire
Iñárritu called his decision behind casting Galifianakis as Jake "a bet". Galifianakis met the director's criteria of being lovable and funny, but Iñárritu also considered him sensitive, which scored him the role. Emma Stone already knew she wanted to work with Iñárritu before she was offered the role of Sam. The script that Iñárritu gave her and the rest of the cast came with the photo "Man on Wire", which featured Philippe Petit crossing the Twin Towers on a tightrope. Iñárritu told the cast, "We are doing that".
