In October 2014, Marvel announced the initial line up of films that would comprise Phase 3, scheduling releases all the way up to 2019 and showing they were heading in a lot of new directions. Those who had criticised the studio for a lack of onscreen diversity were overjoyed to hear that Black Panther and Captain Marvel were both set to headline their own movies, but once the excitement died down, a huge omission became apparent. Despite building a dedicated fan base through numerous appearances in the Marvel Cinematic Universe, a potential Black Widow movie was still nowhere to be seen. This oversight has generated a lot of controversy among fans who feel that Black Widow is ignored time and time again in favour of her male team mates. If you couple that with the glaring lack of Black Widow merchandise, it soon becomes clear that a solo Marvel movie starring Scarlett Johansson is extremely low on the studios agenda, despite her being their most important female character to date. Fans are holding out hope that one of the recently announced mystery films scheduled for release in 2020 could be a solo Black Widow movie. We hate to disappoint you guys, but here are 10 reasons why this will never happen. Trust us. We're as unhappy about this as you are.
