A road movie is a genre of film in which the main characters leave home on a road trip, typically altering the perspective from their everyday lives. Road movies often depict travel in the hinterlands, with the films exploring the theme of alienation and examining the tensions and issues of the cultural identity of a nation or historical period; this is all often enmeshed in a mood of actual or potential menace, lawlessness, and violence, a "distinctly existential air" and is populated by restless, "frustrated, often desperate characters". The setting includes not just the close confines of the car as it moves on highways and roads, but also booths in diners and rooms in roadside motels, all of which helps to create intimacy and tension between the characters. Road movies tend to focus on the theme of masculinity, some type of rebellion, car culture, and self-discovery. The core theme of road movies is "rebellion against conservative social norms".
