Plot

Why It Was Cancelled
Gina Prince-Bythewood, who was to direct the film, was unhappy with the script which led to an indefinite delay in production while she and Sony re-developed the project.

Result
The film was cancelled in August 2018 and is expected to be re-worked into two separate films, starting off with a solo film focusing on Black Cat and another about Silver Sable following afterwards.
