Disney has bought the distribution and marketing rights for all future movies in the Indiana Jones franchise. Under the terms of the deal, Paramount maintains distribution rights for the original trilogy, plus this other movie called Kingdom of the Crystal Skull, if anyone wants to fess up to that.
