A film series is a collection of related films in succession. Their relationship is not fixed, but generally share a common diegetic world. Sometimes the work is conceived 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.
Harry Potter is the most successful film series, surpassing the Star Wars and James Bond series.[1] The Wong Fei Hung film series is the longest film series with 89 films.
