In late 2014, various reports suggested that this project, planned for CBS, could tie into the shared universe of two other hit superhero shows, Arrow (2012) and The Flash (2014), which air on The CW, but are also co-owned by CBS.

The project went through a long and intensive casting process in order to find an actress to play the title character. In January 2015, it was announced that Melissa Benoist had been cast as the lead. Benoist had long been considered a favorite for the role, while other actresses who were considered include Claire Holt, Gemma Atkinson and Elizabeth Lail.
