Les Tontons flingueurs

The film was not popular with critics upon its first release in 1963, but was popular with the public. Its reputation has grown over the years to cult status and it is now a French television classic, with snatches of dialogue and names of characters (like the prostitute Lulu la Nantaise) becoming part of popular culture. Its DVD version, released in 2002, sold 250,000 copies.
One of the most famous scenes is set in a kitchen where the gangsters try to make conversation while drinking a vile and strong liquor. Screenwriter Michel Audiard considered the scene useless but director Lautner included it in homage to the film noir ''Key Largo''. Provided by Wikipedia
