Captain Marvel has topped $1 billion at the worldwide box office. The movie currently stands at $358M domestic and $645M international. It is an impressive feat regardless of the circumstances, but the 21st Marvel Studios film has reached this milestone in unprecedented fashion.

Captain Marvel is the tenth superhero-based movie to amass $1 billion in global receipts. It is the first, however, to do so without being a sequel or team-up, or featuring a character that has previously appeared in another film (showing just her logo on a pager in the Avengers: Infinity War post-credits scene doesn’t count).

Six Marvel Studios films have reached this milestone before, but they are all sequels or team-ups with the exception of Black Panther. The title character of that film, however, was featured prominently in Captain America: Civil War.

Warner Bros. has released three DC-based movies that surpassed $1 billion. The Dark Knight and The Dark Knight Rises were sequels while Aquaman starred a character with a cameo in Batman v Superman: Dawn of Justice and a much more significant appearance in Justice League.

It is fair to argue that previous appearances of their respective title characters in other films were not among the main reasons Black Panther and Aquaman joined the billion-dollar club.  Even so, Captain Marvel remains in a class by itself in superhero-based box office history.
