Birds of Prey (and the Fantabulous Emancipation of One Harley Quinn) has already undergone a significant change, only a few days after arriving in theaters. Movie theater chains have updated the film's title on their websites to now read Harley Quinn: Birds of Prey, putting Margot Robbie's star character at the forefront.

Below are screenshots from AMC Theatres, with the first showing the original title as of today at 5:06 GMT on the Wayback Machine, and the second displaying the updated Birds of Prey title. Cinemark and Regal also reflect the same name change. Though it should be noted that Fandango still has the original title at the time of this writing.

These changes come only four days after the film's Thursday night release. Birds of Prey failed to meet box office expectations during its opening weekend, earning just $33.3 million domestically, which is nearly $20 million below its initial box office projections.

Directed by Cathy Yan from a script by Christina Hodson, Birds of Prey (and the Fantabulous Emancipation of One Harley Quinn) stars Margot Robbie, Jurnee Smollett-Bell, Mary Elizabeth Winstead, Rosie Perez, Ewan McGregor, Ella Jay Basco, Steven Williams, Derek Wilson, Dana Lee, Francois Chau, Charlene Amoia, Chris Messina and Matthew Willig. The film opens Feb. 7.
