Lawrence Kasdan.
Lawrence Kasdan wrote the screenplay for Raiders of the Lost Ark in 1981, and Star Wars films The Empire Strikes Back and Return of the Jedi.
On December 30, 1997, the website Ain't It Cool News sparked the rumor that Kasdan was again hired by Steven Spielberg and George Lucas to write the the fourth Indiana Jones film.[1] However, the rumor was later revealed as false.
