Action
Action movies are often based on comic books and adhere to the theme of overcoming a threat to a person, institution or even civilization itself. They regularly have large budgets and are known as crowd pleasers as they tend to be very popular with audiences. Popular action films include the Avengers and James Bond franchises, which tend to be a common feature of the action movie genre.
Comedy
Comedy is considered to be one of the harder genres of films to make, despite the fact that they are often light on plot and don’t require special effects or large budgets to make. Comedy films such as The Hangover and American Pie are modern examples, while Some Like It Hot with Marylin Monroe, made in 1959, is considered to be one of the best comedies ever made.
Historical
Historical films cover a wide range of film ranging from the costume drama to epic war movies. While these films are often based on fact, they can be fictional accounts of a particular time or period in history. These films can be low or big 
budget but when they are the latter they are often referred to as epics. Famed examples of historical films are the 1959 classic Ben-Hur, Schindler’s List, and Titanic. Historical films are known for winning many awards.
Horror
Horror films can either be a niche product or mainstream and often prey on our fears to evoke a sense of terror while watching the movie. They can be realistic or incorporate a wide range of special effects and cross over into other genres such as sci-fi and psychological. There are also many sub-categories of such a teen horror and slasher horror. Famous horror films include the Haloween movies, the Scream franchise and the 80s hit, Carrie with Sissy Spacek.
Musicals
In the early years of cinema with sound, musical films were very mainstream and formed a major part of the cinema lexicon. However, they began to die out in the 70s and laid dormant for many decades but have recently enjoyed a resurgence. Old musical favorites include Oklahoma, The Wizard of Oz, Grease and the Sound of Music while modern musical hits include Les Miserables, Chicago, and the ever-popular Mamma Mia.
