Actress DeWanda Wise just boarded the Captain Marvel movie project in January, but it looks like she is already departing the film. Apparently she had a scheduling conflict with the Netflix series She's Gotta Have It, which she appears in. The series was renewed for a second season at around the same time she joined Captain Marvel.
The role that Wise had in Captain Marvel was never specified and no word of a replacement was announced, or how much the loss of Wise would affect production. Captain Marvel is targeting a March 8, 2019 launch.
