Development In May 2016, ahead of the release of
Suicide Squad,
Warner Bros. Pictures announced a spin-off film focusing on
Harley Quinn and several other female
DC Comics heroes and villains, such as
Batgirl and the
Birds of Prey.
Margot Robbie was attached to reprise her role as Harley Quinn and would also serve as producer. British screenwriter
Christina Hodson was announced to be writing the film in November. Robbie had
pitched the film to Warner Bros. in 2015 as "an
R-rated girl
gang film including Harley because I was like, 'Harley needs friends.' Harley loves interacting with people, so don't ever make her do a standalone film". Robbie felt it was important for the film to have a female director. While Warner Bros. and
DC Films had various other Harley Quinn-oriented films in development,
Birds of Prey was the only one in whose development Robbie was directly involved. Robbie spent three years working on
Birds of Prey and continued to present it to Warner Bros. until the studio felt the project was at the point it could be made. Yan pitched for the job as "wanting to smash the patriarchy." Robbie was confirmed to be producing the film under her
LuckyChap Entertainment banner as part of a first-look deal with the studio; Sue Kroll and Bryan Unkless were also announced to serve as producers through their companies Kroll & Co. Entertainment and Clubhouse Pictures, respectively. Production was scheduled to begin by late 2018 or early 2019. The
Penguin was intended to appear in the script at one point but was dropped to preserve his appearance in
The Batman. Barbara Gordon (also known as Batgirl), is founding member of the team in the comics, but was removed from
Birds of Prey due to the then planned Batgirl film, also written by Christina Hodson.
Pre-production By July 2018, the film was entering pre-production. Robbie confirmed the film would be titled
Birds of Prey, describing it as "different" from the other DC films featuring Harley Quinn, and said it would be produced on a relatively small budget compared to other superhero films. She also stated Harley Quinn would receive a new costume and teased the casting of diverse actors. The line-up for the Birds of Prey team was revealed to include
Black Canary,
Huntress,
Cassandra Cain, and
Renee Montoya, with the villain set to be a Batman adversary who had not yet
been seen in the films. Casting began in August, with Warner Bros. considering several actresses for Huntress and Black Canary.
Alexandra Daddario,
Jodie Comer,
Blake Lively, and
Vanessa Kirby expressed interest. In August,
Roman Sionis / Black Mask was revealed to be the film's antagonist.
Janelle Monáe,
Gugu Mbatha-Raw, and
Jurnee Smollett-Bell were under consideration for Black Canary by September, while
Sofia Boutella,
Margaret Qualley,
Mary Elizabeth Winstead and
Cristin Milioti were being considered to play Huntress.
Justina Machado and
Roberta Colindrez tested for Renee Montoya, while Warner Bros. began seeking a 12-year-old Asian actress to play Cassandra Cain. In late September, Smollett-Bell and Winstead were respectively cast as Black Canary and Huntress, Warner Bros. scheduled a February 7, 2020, release date, and
Ewan McGregor and
Sharlto Copley were under consideration for the role of Black Mask. During the U.S.-China Entertainment Summit in October, Yan confirmed the cast and that the film would be R-rated. She said, "[I] could not put the script down, it had so much dark humor to it, which a lot of my work does, and there are themes of female empowerment which are so strong and relatable." Cinematographer
Matthew Libatique joined the film that month, as did
Rosie Perez as Renee Montoya. Stunt coordinator Jonathan Eusebio and fight coordinator Jon Valera joined in November, and McGregor as Black Mask and
Ella Jay Basco as Cassandra Cain. Robbie revealed the full title, and said the subtitle reflects the film's humorous tone. Production designer
K. K. Barrett joined in December, as did
Chris Messina as
Victor Zsasz. Although filming had been expected to also take place in
Atlanta and
Savannah, Georgia, the entire shoot took place in Los Angeles after the production received a
tax credit from California. In February,
Charlene Amoia joined the cast.
Post-production Jay Cassidy and Evan Schiff served as editors, while
Method Studios,
Weta Digital,
Luma Pictures,
Image Engine, and
Crafty Apes provided the
visual effects for the film. In August 2019,
Chad Stahelski served as a
second unit director for reshoots, his company 87eleven having been already involved in developing the action scenes. Photography for the additional footage began on September 3, 2019. Costume concept artist Greg Hopwood released an exclusive look at Costume production art at
San Diego Comic-Con in July 2019. Talking about the post-production process, Cathy Yan indicated that she "would have loved to have more control over the edit, but that's just kind of how it is. I don't know if there's a Cathy Yan cut out there, but I think for any filmmaker, all of us are in it because we want to express ourselves as wholly as possible. And to match what you ultimately see on screen with what's in our head". == Music ==
