Bad Lieutenant

Bad Lieutenant is a 1992 American neo-noir crime drama film directed by Abel Ferrara, from a screenplay co-written with Zoë Lund. It stars Harvey Keitel as the title character "bad lieutenant", an unnamed and corrupt New York police officer, who suffers a string of personal and spiritual crises.

The film premiered at the 1992 Cannes Film Festival, where it screened in the Un Certain Regard section. Due to its graphic violence and drug use, the film was released in the United States with an NC-17 rating. Despite limited theatrical distribution, it received widespread critical praise, and has become one of Ferrara's best-known and most appreciated works. Martin Scorsese named this movie as one of the best movies of the entire 1990s.

A follow-up film entitled Bad Lieutenant: Port of Call New Orleans, also produced by Edward R. Pressman, was released in 2009. Despite sharing a title and a similar premise, it was described as being "neither a sequel nor a remake".
