The main factors that influence the types of films that are made today are popular culture, the advance in technology within the production of film, target audiences and ultimately how much money producers think a film will make.
In some ways popular culture dominates what films are made. Most of the best selling films of 2015 were either bestselling books, comic book movies or true story movies that have some relevance to society today. Like The Avengers Age of Ultron for example made $191,271,109 in its opening weekend. Marvel films have proved many times over that they are capable of bringing in a lot of money so they will keep making marvel movies until they don't. Part of the reason that people like marvel films is that it is one interlocking universe within which all the films takes place. The Avengers takes place in the same universe that The Guardians of the Galaxy does. All of the Marvel films were already popular comic books before they were films and the popularity of films such as The Hunger Games was also certain due to the Book being a bestseller before it was made into a movie script. Producers will often use stories that have already proven to be popular so there will be less of a chance of the film flopping.
