Though Disney obtained Indiana Jones as an IP when they acquired Lucasfilm, the distribution rights to the first four movies, plus The Young Indiana Jones Chronicles, remain controlled by Paramount. Consequently, they’ve never appeared on Disney’s streaming service. Many have asked when that situation would change. The answer, of course, was “when they paid up.”
With a new movie to promote, Disney evidently felt the time was right to play ball with Paramount, and the latter hasn’t exactly been shy about leasing out the movies for cash anyway, with the series regularly disappearing from Paramount’s own service while they were licensed to the highest bidder. It looks like the Mouse bought their turn, and so starting May 31st, Disney+ will be streaming the Indy catalog on a nonexclusive basis (they will continue to be available on Paramount+), the better to leverage that sweet brand extension. Finally, a victory for corporations.
