Recommendations

For further research, the interviewees should be people who have affirmed that they like movies and have seen many different kinds. Again, there were too many "I dunno" answers. Also, there should be more questions. ("Do you have a favorite actor? Do most of his/her roles have similar personalities? Do they speak the same way?") 

I think there should me more research done on how movie language (not just cursing) affects box office performance. It would be interesting to see if a movie featuring stupid characters who speak in stupid ways would do better than a movie with actually intelligent characters.
