Buddy cop

A buddy cop film is a film with plots involving two people of very different and conflicting personalities who are forced to work together to solve a crime and/or defeat criminals, sometimes learning from each other in the process. The two are normally cops, but some films, such as 48 Hrs. (a cop and a con), that are not about two cops may still be referred to as buddy cop films. It is a subgenre of buddy films.

Frequently, although not always, the two heroes are of different ethnicity or cultures. However, regardless of ethnicity, the central difference is normally that one is "wilder" than the other: a hot-tempered iconoclast is paired with a more even-tempered partner. Often the "wilder" partner is the younger of the two, with the even-tempered partner having more patience and experience. These films sometimes also contain a variation on the good cop/bad cop motif, in which one partner is kinder and law-abiding, while the other is a streetwise, "old school" police officer who tends to break (or at least bend) the rules. Another frequent plot device of this genre is placing one of the partners in an unfamiliar setting (like a different city or foreign country) or role (like requiring police field work of a non-cop, rookie, or office-bound "desk jockey"). In these cases, they are usually guided by the other partner.

In his review of Rush Hour, Roger Ebert coined the term "Wunza Movie" to describe this subgenre, a pun on the phrase "One's a..." that could be used to describe the contrasts between the two characters in a typical film.

The cliché was satirized in the film Last Action Hero. While the movie in itself was a buddy cop film (i.e. pairing a fictional cop with a real world boy), the film's police department obligatorily assigned all cops a conflicting buddy to work with, even to the extreme of one officer being partnered with a cartoon cat.

A subgenre of the buddy cop film is the buddy cop-dog movie, which teams a cop with a dog, but uses the same element of unlikely partnership to create comedic hijinks. Examples include Turner & Hooch, Top Dog and K-9.
