Scarlett Johansson pays Kaa, the hypnotic python, in Disney?s new live action version of ?The Jungle Book.? When interviewed about the role, Johansson stated, ?It?s a boy snake in the cartoon. And also, he?s a much? friendlier version of our Kaa. He?s really kind of goofy in the film and friends with Mowgli and kind of follows him along. In this film, Kaa is more of a storyteller, and she?s very seductive. She?s a mirror into the past for Mowgli.?
