A couple of days ago big comic book websites noticed that many online ticket sites had changed the title of Birds of Prey to “Harley Quinn: Birds of Prey”. They quickly wrote up elaborate and sensational think pieces about the change and how it was a sign of Warner Brothers changing course for the movie.
Unfortunately, it’s not a true title change.
According to Atom Ticket’s Alisha Grauso, the title change is only for online ticketing and not an official change from the studio:
Update on the #BirdsofPrey title change: It's apparently for display/search purposes only for vendors and theaters, not an official title change. Just to clarify for those of you writing about it. ??♀️— Alisha Grauso (@AlishaGrauso) February 11, 2020
When Warner didn’t issue new posters or change any of the official websites (DC Comics or Warner Brothers) to reflect a changed title, it seemed to be a false alarm, and it turns out it is.
