A few days ago, it was announced that Harley Quinn: Birds of Prey would soon be available for rent online from March 24.
After the box office success of Suicide Squad, the character of Harley Quinn as played by Margot Robbie was considered the breakout star of the film.
Soon after, Robbie made a deal with Warner Bros. to produce a standalone Harley Quinn feature, which evolved into the Birds Of Prey (And the Fantabulous Emancipation of One Harley Quinn) project under director Cathy Yan that was finally released in theaters.
So they decided to change the title of the feature to Harley Quinn: Birds of Prey to draw more attention to the one character in the movie who is already a fan favorite.
