This is a confusing question, because first it asks to compare the literary genre of drama to other literary genres, and then it asks for a comparison of literature to film, a different medium.
Drama is a very broad genre that can have many subgenres, similar to other big genres like Romance, Mystery, and Science-Fiction. Drama is also a genre that can be shared in a single piece of literature. Many books don't have just one genre, and drama can easily be paired with other genres like Drama/Historical, or NonFiction-Drama. Romeo and Juliette is a classic example of Drama/Romance.
In the film sense, drama is nearly everywhere. Even in non-fiction stories or documentaries, there is a dramatic quality to the portrayal of the events depicted. For example, the true story of Captain Philips was dramatized in the movie Captain Philips with Tom Hanks. Another Tom Hanks movie called Sully was made after the plane pilot who crash-landed the plane on the Hudson River. Both of these films took true stories and edited small details to make the story worthwhile to watch in theaters.
