Movie series

A film series or movie series (which is also referred to as a film franchise or movie franchise) is a collection of related films in succession that share the same fictional universe, or are marketed as a series.
Description.
Sometimes the work is conceived from the beginning as a multiple-film work – for example, the "Three Colours" series – but in most cases the success of the original film inspires further films to be made. Individual sequels are relatively common, but are not always successful enough to spawn further installments.
The 25 films (as of 2021) of the Marvel Cinematic Universe form the highest grossing film series even when adjusted for inflation, surpassing J. K. Rowling's Wizarding World (10 films) "Star Wars" (11 films), Ian Fleming's James Bond (25 films), and J. R. R. Tolkien's Middle-earth (6 films) series.
