Twins is a 1988 American buddy comedy film produced and directed by Ivan Reitman. The film is about unlikely fraternal twin brothers who were separated at birth. The core of the film is the contrast between the streetwise Vincent (DeVito) and the intelligent but naive Julius (Schwarzenegger).

The buddy film is a subgenre of romantic comedy, a combination of the romance, adventure and comedy film in which two people, bonded through some kind of affection or love for each other, go on an adventure, mission, or road trip. The two typically are males with contrasting personalities. The contrast is sometimes accentuated by an ethnic difference between the two. The buddy film is commonplace in Western cinema; unlike some other film genres, it endured through the 20th century with different pairings and different themes.
