Film-making is a business just like various other professions and the ultimate goal of every business is to make a good and big profit. As far as motivation is concerned, when a movie is made which can captivate the audience, the likes and dislikes of the public are very important for that. When a movie repeats the history of the country or a particular event, then such a movie affects the audience more, perhaps because of this they also make more profit, and movie makers are more encouraged to make more such movies in the future. Along with this, many times a trend comes of movies which also changes on the basis of the preference and situation of the society, like at one time movies with the philosophy of love, hate, etc. were more preferred, same today on action, science-related or true events. Movies based can be found to be more popular.
