Development of a Black Widow film began in April 2004 by Lionsgate, with David Hayter attached to write and direct. However, the project did not move forward and the film rights to the character reverted to Marvel Studios by June 2006. Johansson was cast in the role for several films set in the MCU, beginning with Iron Man 2 (2010).
Marvel and Johansson expressed interest in a potential solo film several times over the following years, before development progressed with the hiring of Schaeffer and Shortland in 2018. Benson was hired and further casting took place in early 2019. Filming began in May, taking place in Norway and at Pinewood Studios in England. Production is expected to last until September.
