Question: When did first star wars movie come out?

Disambiguated questions and answers:
context: "Star Wars" was released in a limited number of theaters in the United States on May 25, 1977, and quickly became a blockbuster hit, leading to it being expanded to a much wider release. The film opened to critical acclaim, most notably for its groundbreaking visual effects. It also earned notable praise for its musical score, action sequences, characterization, themes, and performances of the cast (particularly that of Guinness). It grossed a total of $775 million, surpassing "Jaws" (1975) to become the highest-grossing film at the time until the release of "E.T. the Extra-Terrestrial" (1982). When adjusted for inflation, "Star Wars" is the second-highest-grossing film in North America (behind "Gone with the Wind") and the fourth-highest-grossing film in the world. It received ten Oscar nominations (including Best Picture), winning seven. In 1989, it became one of the first films to be selected as part of the U.S. Library of Congress's National Film Registry as being "culturally, historically, or aesthetically significant." At the time, it was the most recent film in the registry and the only one chosen from the 1970s. In 2004, its soundtrack was added to the U.S. National Recording Registry. Today, it is regarded as one of the most important films in the history of motion pictures.
