The original Star Wars story and screenplay were created and primarily written by George Lucas. He began writing the scripts in the early 1970s and developed the story, which was inspired by mythology, classic films, and the concept of the hero's journey. Lucas wrote four different screenplays before settling on the final version for the original 1977 film, Star Wars (later titled "Star Wars: A New Hope").
Other writers have contributed significantly to the expanding Star Wars saga, particularly during the production of the original trilogy and subsequent films. For example, Leigh Brackett and Lawrence Kasdan played major roles in writing "The Empire Strikes Back," while Kasdan also co-wrote "Return of the Jedi" alongside Lucas. Novelizations and expanded universe works were often written by other authors such as Alan Dean Foster and Timothy Zahn, who contributed stories that extended the Star Wars universe.
In summary, George Lucas is the original creator and main writer of the Star Wars story and screenplay, with many other writers collaborating over the years to build the franchise further.
