VIDEO : 'Avengers: Infinity War' Directors Talk Black Widow Hair Change

Avengers: Infinity War directors Anthony and Joe Russo say the new hairstyle rocked by Scarlett Johansson's Black Widow is another reaction to the leftover fallout from Captain America: Civil War. Fielding fan questions on Build, the directing duo elaborated on why it was necessary for Widow to change her fiery red hair to a more understated blonde: ?At the end of Captain America: Civil War, Black Widow of course sided with Cap?s side ultimately, so she was with that group of Avengers that was no longer legal or sanctioned by the government. So they basically had to go underground,? answers Anthony Russo.
