This marks one of the lowest modern debuts for a superhero film, according to the report.

The Margot Robbie-led film was originally expected to debut somewhere between $50-55 million. At the same time, it was never expected to pull in massive numbers due to being a spinoff, and having an R rating.

Prior to Birds of Prey, the lowest DC Extended Universe film was Shazam! with $53 million.
