> George Lucas initially hired Leigh Brackett, the sci-fi novelist who also wrote screenplays for Howard Hawks—including The Big Sleep (1946)—to write the sequel to Star Wars (1977). Brackett died in March 1978 while the film was still in pre-production, though, and Lucas wasn't satisfied with her script. Lucas wrote the next draft himself, which established structure and twists close to the final film, but suffered from dialogue. When Kasdan delivered his script for Raiders, Lucas asked him to rewrite The Empire Strikes Back. Kasdan suggested he read Raiders first, but Lucas reportedly said: "If I hate Raiders, I'll call you up tomorrow and cancel this offer, but basically I get a feeling about people."[9]

Brackett was a sci-fi author, Kasdan was a screenwriter by trade.

Despite seeming like similar tasks, screenwriting and book-writing actually have pretty distinct skillsets in some ways.
