Why do some movies have sequels and prequels?

Movies are an art form that has been around for over a century. Sequels and prequels are a way for movie studios to capitalize on the success of a particular movie or franchise. There are a few reasons why sequels and prequels are made:

• Financial Gain: Movie studios are businesses, and their primary goal is to make money. Sequels and prequels are a safe bet for movie studios because they already have an established audience that is familiar with the characters and storylines. This familiarity often leads to higher box office numbers.
• Story Expansion: Sequels and prequels allow filmmakers to expand on the story and characters of the original movie. This can be beneficial if the original movie left some unanswered questions or if there are other storylines that can be explored.
• Fan Service: Some movies have a loyal fan base that enjoys the characters and world of the movie. Sequels and prequels can be made to satisfy the fans and give them more of what they love.

Sequels and prequels are not always successful, and there have been many examples of movies that were not well received by audiences or critics. However, when done well, sequels and prequels can be just as entertaining and successful as the original movie.

It is important to note that not all movies need sequels or prequels. Some movies are best left as standalone films, and trying to expand on the story can take away from the original movie's impact.
