Dogma is a 1999 American adventure fantasy comedy film written and directed by Kevin Smith, who also stars in the film along with an ensemble cast that includes Ben Affleck, Matt Damon, Linda Fiorentino, Alan Rickman, Bud Cort, Salma Hayek, Chris Rock, Jason Lee, George Carlin, Janeane Garofalo, Alanis Morissette, and Jason Mewes.

Brian O'Halloran and Jeff Anderson, the stars of Smith's debut film Clerks, have cameo roles, as do Smith regulars Scott Mosier, Dwight Ewell, Walt Flanagan, and Bryan Johnson.

The fourth film set in the View Askewniverse is a hypothetical-scenario film revolving around the Catholic Church and Catholic belief, which caused organized protests and much controversy in many countries, delaying release of the film and leading to at least two death threats against Smith. The film follows two fallen angels, Loki and Bartleby, who, through a loophole in Catholic Dogma, find a way to get back into Heaven after being cast out by God. However, as existence is founded on the principle that God is infallible, their success would prove God wrong and thus undo all creation. The last scion and two prophets are sent by the Voice of God to stop them.

Dogma is the established belief or doctrine held by a religion, or a particular group or organization. It is authoritative and not to be disputed, doubted, or diverged from, by the practitioners or believers. Although it generally refers to religious beliefs that are accepted without reason or evidence, they can refer to acceptable opinions of philosophers or philosophical schools, public decrees, or issued decisions of political authorities. The term derives from Greek δόγμα "that which seems to one, opinion or belief" and that from δοκέω (dokeo), "to think, to suppose, to imagine". Dogma came to signify laws or ordinances adjudged and imposed upon others by the First Century. The plural is either dogmas or dogmata, from Greek δόγματα. Today, It is sometimes used as a synonym for systematic theology.

Dogmata are found in religions such as Christianity, Judaism, and Islam, where they are considered core principles that must be upheld by all followers of that religion. As a fundamental element of religion, the term "dogma" is assigned to those theological tenets which are considered to be well demonstrated, such that their proposed disputation or revision effectively means that a person no longer accepts the given religion as his or her own, or has entered into a period of personal doubt. Dogma is distinguished from theological opinion regarding those things considered less well-known. Dogmata may be clarified and elaborated but not contradicted in novel teachings (e.g., Galatians 1:6-9). Rejection of dogma may lead to expulsion from a religious group.

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.
