9 is a 2009 American computer-animated science fiction action/adventure film directed by Shane Acker and produced by Tim Burton and Timur Bekmambetov. The film stars the voices of Elijah Wood, John C. Reilly, Jennifer Connelly, Crispin Glover, Fred Tatasciore, Martin Landau and Christopher Plummer. It is based on Acker's Academy Award-nominated 2005 short film of the same name. The screenplay for the film was written by Pamela Pettler, with casting by Mindy Marin, production design by Robert St. Pierre and Fred Warter, and art direction by Christophe Vacher.

Prior to the events of film, a scientist is ordered by his dictator to create a machine in the apparent name of progress. The Scientist uses his own intellect to create the B.R.A.I.N., a thinking robot. However, the dictator quickly seizes it and integrates it into the Fabrication Machine, an armature that can construct an army of war machines to destroy the dictator's enemies. Lacking a soul, the Fabrication Machine is corrupted and exterminates all organic life using toxic gas. In desperation, the Scientist uses alchemy to create nine homunculus-like ragdolls known as Stitchpunks using portions of his own soul via a talisman, but dies as a result.

The year 2009 saw the release of many films. Seven made the top 50 list of highest-grossing films, and the Academy of Motion Picture Arts and Sciences announced that as of this year, their Best Picture category would consist of ten nominees, rather than five (the first time since the 1943 awards).

These are the top grossing films that were released in 2009. The top ten films of 2009, by worldwide gross in United States dollars, as well as the United States, Canada, United Kingdom, and Australia grosses, are as follows:

Avatar has grossed over $2.7 billion, making it the highest-grossing film in history, as well as one of two films in history to gross $2 billion (the second being Titanic, also by James Cameron, during its 3D re-release) in box office receipts and the first film to gross over $700 million in the US and Canada. 7 films (Harry Potter and the Half-Blood Prince, Ice Age: Dawn of the Dinosaurs, Transformers: Revenge of the Fallen, 2012, Up and New Moon) are among the top 50, making this the year with the highest representatives in the top 50 highest-grossing films of all time.

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.
