Similarly, the Marvel Cinematic Universe is listed on the above websites as consisting of 23 films released however, these are also listed separately as 4 "Avengers" films, 3 "Iron Man" films, 3 "Captain America" films, 3 "Thor" films and so on; for these tables, the films have similarly been treated as separate series. A similar approach has been taken to the "Wizarding World" series (where the films are split  between the "Harry Potter" film series and the "Fantastic Beasts" film series); the "X-Men" film series (where there are separate film series for Wolverine and Deadpool); "Star Trek" (where there are separate film series for "", "" and a later reboot); and the multiple "Spider-Man", "Batman" and "Planet of the Apes" film series.
