The synopsis for the film is as follows:
Since the events of Suicide Squad, Harley Quinn has left the Joker. Batman has disappeared, leaving Gotham City unprotected from crime. When a young girl named Cassandra Cain comes across a diamond belonging to crime lord who goes by the name of Black Mask, Harley joins forces with Black Canary, Huntress and Renee Montoya to protect her.
The trailer tailors more toward the ‘Fantabulous Emanicipation of One Miss Harley Quinn’ angle more so than Birds of Prey, but I think it’s more of a commercial angle to bring in those that enjoyed Margot Robbie’s portrayal of Harley Quinn in Suicide Squad, then use the next few trailers to highlight the rest of the main characters.
The film is directed by Cathy Yan and stars Margot Robbie, Mary Elizabeth Winstead, Jurnee Smollett-Bell, Rosie Perez, Ewan McGregor, Ella Jay Basco, Chris Messina, Steven Williams, Derek Wilson, Dana Lee, Francois Chau, Matthew Willig, Charlene Amoia, Robert Catrini and Ali Wong.
Birds Of Prey is scheduled for cinematic release on the 7th February 2020.
