Steven Spielberg is making “Indiana Jones 5.” Although the release date was set for 2020, the film might be released later with the recent switch in writers. According to Screenrant, David Koepp has been replaced by Jon Kasan to write the script. Koepp confirmed he is the new writer of the script on Twitter. If the film releases in 2021, it would be 40 years since the first movie of the franchise premiered.
