The buddy film is a subgenre of adventure and comedy film in which two people—often both men—are put together and on an adventure, a quest, or a road trip. The two often contrast in personality, which creates a different dynamic onscreen than a pairing of two people of the opposite gender. The contrast is sometimes accentuated by an ethnic difference between the two. The buddy film is commonplace in American cinema; unlike some other film genres, it endured through the 20th century with different pairings and different themes.
