It was produced by Lucasfilm and distributed by 20th Century Fox, and consists of Star Wars (1977), The Empire Strikes Back (1980) and Return of the Jedi (1983).

It was followed by a prequel trilogy between 1999 and 2005, and a sequel trilogy between 2015 and 2019. Collectively, they are referred to as the "Skywalker Saga" to distinguish them from spin-off films set within the same universe.
