An art house film, also known as an indie film, is a type of movie that is typically produced independently and outside of the mainstream Hollywood system. These films often focus on artistic expression and are usually characterized by their unconventional storytelling and unique visual style. Art house films often explore themes that are not typically found in mainstream films, such as social issues, political themes, and philosophical ideas. They are often seen as a form of alternative cinema, and have become increasingly popular in recent years.
