Unreleased American superhero movie Batgirl is based on the DC character Batgirl, also known as Barbara Gordon. Intended to be a part of the DC Extended Universe (DCEU), it was produced by Burr! Productions and DC Films for the HBO Max streaming service. Leslie Grace played Batgirl in the Adil El Arbi and Bilall Fallah-directed movie, which also starred J. K. Simmons, Jacob Scipio, Brendan Fraser, Michael Keaton, and Ivory Aquino. The screenplay was written by Christina Hodson.

Development of a Batgirl feature film began with Joss Whedon in March 2017, but he left the project a year later. Hodson was hired to write a new script in April 2018, with El Arbi and Fallah hired to direct in May 2021 when the film was confirmed as an HBO Max original. Grace was cast that July, followed by additional castings—including Keaton reprising his role of Bruce Wayne / Batman from Batman (1989) and Batman Returns (1992)—and filming took place in Glasgow, Scotland, from November 2021 to March 2022. In August 2022, DC Films and HBO Max parent Warner Bros. Discovery (WBD) announced that, while the film had entered post-production, the studio no longer planned to release it in 2022 as scheduled due to the company’s cost-cutting measures and a refocus on theatrical releases.
