Larson's casting was announced at the 2016 San Diego Comic-Con International, making it Marvel Studios' first female-led solo film. Boden and Fleck were brought on board to direct in April 2017, and Robertson-Dworet soon took over scripting duties, the story of which borrows elements from the 1971 "Kree–Skrull War" comic book storyline.

By the start of filming, the remainder of the cast was filled out as were the additional screenwriters. Filming concluded in July 2018.
