A lot of big movies are being released in September, which has led to a ton of September 2023 box office predictions. The summer lineup of movies led to a number of surprises, such as the R-rated, three-hour biopic Oppenheimer grossing $800 million, Barbie becoming the highest-grossing movie of the year, and a shocking number of box office bombs. The Flash, Indiana Jones and the Dial of Destiny, and Haunted Mansion were just a few failures of summer 2023. However, the summer box office is now in the rearview mirror, and September's releases could be more positive for the industry.
