A movie's opening sequence sets the mood and pacing of the story. It is meant to capture the interest of the viewers early on in the film. The style and treatment for it largely depends on the director's vision.
While others simply feature a typical sequence without additional effects or texts, an opening sequence may also showcase accompanying opening title effects or superimposed texts that show the names of the studios involved in the project and the film's main cast and crew. Some of the most engaging opening sequences that are often remembered by moviegoers include those from the classic movies "Star Wars: Episode 4: A New Hope," "Full Metal Jacket," and "The Lion King."
