Hybrids

As genre and film has changed and has progressed throughout time, many narratives and story lines has changed the ways in which these genres of film has been produced. Because of high demand of a certain 'genre' when in its prime, producers have found it hard to create many story lines to fit the typical conventions of a certain genre, so as time has passed genres have developed into things called sub genres or hybrids. 

A hybrid is when the conventions of two genres are collaborated together by the writers of film to create a film containing elements of both genres for a new type of film. Hybrid films exist as there are only a certain amount of story lines and narratives that can fit within a film of one genre without conventions of others,  so this repetition lost the interest of the film producers audience. Hybrid films were then created as something new for the audience, as a creative storyline of the two genres gave the audiences something new and unseen which makes them want to watch the films and keeps the audience seeming a corporations films. 

An example of a Hybrid film would be Back to the Future. This is because of its collaboration of genres between science fiction, with the time travel and futuristic car, and romance as the main has to ensure not to fall in love to save his future of existence. This collaboration of genres then made the film successful as it contained twists which were added as two genres conventions were combined to form this difference in the film which was different from a typically Sci fi or Romance film. This then made the film appealing to a larger audience and the film became even popular because of this.
