People who study movies think about them in different and divergent ways. Scholars have explored sociological issues (race, ethnicity, religion, and class as depicted in films) and psychological issues (how movies express otherwise hidden ideas about gender and sexuality, for instance, or how audiences respond to comedies as opposed to horror films), to cite only a few of the various lenses through which we can view films. Researchers can devote themselves entirely to the study of film history—the nuts-and-bolts names, dates, and ideas of technological and aesthetic innovation that occurred on a global level.
