Yes, it is finally happening! Disney, which purchased the film rights to the Indiana Jones franchise from Paramount in 2013, just announced that there will be a new Indiana Jones film with the old gang – Harrison Ford will star, Steven Spielberg will direct, Frank Marshall and Kathleen Kennedy will produce. The film is planned to be released on July 19th, 2019.
Marshall and Kennedy have been involved at the start – the two, married in 1987, were both involved starting with Raiders of the Lost Ark – Marshall as producer, and Kennedy as the assistant to Spielberg, and both cofounded Amblin Entertainment with Spielberg. Kennedy is now the president of Lucasfilm after the acquisition by Disney.
No mention of Shia LaBeouf, who was the heir apparent to the franchise when Indiana Jones and the Kingdom of the Crystal Skull was released in 2008 – until that film nearly sunk the franchise. Whether they will try again to pass the fedora on is unsure, but it is expected to involve younger actors.
