Creed III has now outgrossed all but one of the previous films in its franchise. In addition to being the third film in the Creed trilogy, the Michael B. Jordan directorial outing is a spinoff of the Rocky franchise, which began with the Best Picture-winning original in 1976. When Creed III, which pits Jordan's Adonis Creed against a new competitor played by Jonathan Majors, opened on March 3, it not only grossed the highest opening weekend of the franchise, but of the entire sports film genre.
