James Gunn has spoken, on more than one occasion, about his affectionate, but complicated, relationship with his Superman<\/a>\u00a0<\/em>star David Corenswet\u2014going so far, in one interview<\/a>, as to compare him to the film\u2019s uncontrollable super-dog, Krypto. (In the past, Gunn has noted that he\u2019s used to working with more straightforward, \u201cGet it done\u201d actors, and was less accustomed to Corenswet\u2019s need to question and analyze the emotional validity of pretty much every line that comes out of his mouth.) Now, Gunn has gone a little further and posted video proof of how the two men\u2019s different approaches produced some of Superman<\/em>\u2018s best moments, releasing on social media this weekend<\/a> footage of him and his star getting into a complicated, emotionally charged on-set back-and-forth about the film\u2019s big philosophical climax.<\/p>\n Edited together as part of a 60-minute making-of feature, the seven-minute video shows Gunn walking Corenswet through Superman\u2019s big final confrontation with Nicholas Hoult\u2019s Lex Luthor, and specifically the moment when the Man Of Steel reminds Luthor he\u2019s just as human as the rest of us. What plays out on screen is fascinating: You can watch Corenswet working to hit the beats his director is asking him to nail, playing the moment angry, and a little defiant. But then, in Gunn\u2019s words, \u201cDavid stops, and I\u2019m like, oh no, David\u2019s doing his thing.\u201d Corenswet specifically questions whether the moment negates one of the scenes at the movie\u2019s heart, a conversation between Clark and Pa Kent. (\u201cI feel weak with me yelling at him,\u201d Corenswet remarks of the Luthor fight.) Gunn notes that the whole argument was taking place while the two men were 50 feet away from each other, on a crowded set\u2014until Corenswet walked off set to talk to his director directly, a moment also captured by the behind-the-scenes cameras.<\/p>\n It\u2019s genuinely riveting stuff: No obvious anger or ego, just two guys trying to talk their way through the emotional makeup of one of the movie\u2019s biggest scenes together. It even has a classic Hollywood climax: Gunns\u2019 directives suddenly click for Corenswet, and he strides back onto the set, nailing the monologue with a mixture of strength and vulnerability. Gunn notes that Corenswet wrote him a note later that night saying, \u201cI think that was my favorite day ever on set with a director,\u201d with Gunn wholeheartedly agreeing.<\/p>\n
