To make a successful film the first thing we have to think about is whos going to watch it who would be the audeince. Every film has its significant range of ages or even gender to decide what kind of film or what type of genre. We have to think about what age and this can be seen in our mise en scene or music but the story its self would determine what range of age group that is acceptable.
Gender in some cases is used to who would watch what film however stereotype could also be involved in some peoples opinion. As you can see here females mostly go for romance weres males weould recomend sci fi movies.
