Jonathan Kasdan, co-writer of Solo: A Star Wars Story, reportedly has been brought on by Lucasfilm to replace David Koepp as writer on Indiana Jones 5. As reported by Collider, Kasdan is reportedly taking over writing duties for Koepp after he was originally brought on in 2016 to write the script. It is unclear if Kasdan is starting from scratch, or simply working on Koepp's previously written material at this time.
