Blow is a 2001 biopic about the American cocaine smuggler George Jung, directed by Ted Demme. David McKenna and Nick Cassavetes adapted Bruce Porter's 1993 book Blow: How a Small Town Boy Made $100 Million with the Medellín Cocaine Cartel and Lost It All for the screenplay. It is based on the real life stories of George Jung, Pablo Escobar, Carlos Lehder, and the Medellín Cartel. The film's title comes from a slang term for cocaine.

The film opens to a young George (Johnny Depp) and his parents Fred (Ray Liotta) and Ermine (Rachel Griffiths) of Weymouth, Massachusetts. When George is ten years old, Fred files for bankruptcy and loses everything, but tries to make George realize that money is not important.

As an adult, George moves to Southern California with his friend "Tuna" (Ethan Suplee); they meet Barbara (Franka Potente), an airline stewardess, who introduces them to Derek Foreal (Paul Reubens), the main dealer. With Derek's help, George and Tuna make a lot of money. Kevin Dulli (Max Perlich), a college student back in Boston, visits them and tells them of the enormous market — and demand — for pot in Boston. With Barbara's help, they start bringing the drugs to Boston.

Blow may refer to:

A film, also called a movie or motion picture, is a series of still or moving images. It is produced by recording photographic images with cameras, or by creating images using animation techniques or visual effects. The process of filmmaking has developed into an art form and industry.

Films are cultural artifacts created by specific cultures, which reflect those cultures, and, in turn, affect them. Film is considered to be an important art form, a source of popular entertainment and a powerful method for educating – or indoctrinating – citizens. The visual elements of cinema give motion pictures a universal power of communication. Some films have become popular worldwide attractions by using dubbing or subtitles that translate the dialogue into the language of the viewer.

Films are made up of a series of individual images called frames. When these images are shown rapidly in succession, a viewer has the illusion that motion is occurring. The viewer cannot see the flickering between frames due to an effect known as persistence of vision, whereby the eye retains a visual image for a fraction of a second after the source has been removed. Viewers perceive motion due to a psychological effect called beta movement.
