Hulk (also known as The Hulk) is a 2003 American superhero film based on the fictional Marvel Comics character of the same name. Ang Lee directed the film, which stars Eric Bana as Dr. Bruce Banner, as well as Jennifer Connelly, Sam Elliott, Josh Lucas, and Nick Nolte. The film explores the origins of the Hulk, which is partially attributed to Banner's father's experiments on himself, and on his son.

Development for the film started as far back as 1990. The film was at one point to be directed by Joe Johnston and then Jonathan Hensleigh. More scripts had been written by Hensleigh, John Turman, Michael France, Zak Penn, J. J. Abrams, Scott Alexander and Larry Karaszewski, Michael Tolkin, and David Hayter before Ang Lee and James Schamus' involvement. Hulk was shot mostly in California, primarily in the San Francisco Bay Area. The film was released with mixed reviews and grossed over $245 million worldwide. Marvel Studios rebooted it in 2008 with The Incredible Hulk.

Hulk 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.
