Under the arrangement, Disney gains distribution and marketing
rights to future films, in addition to retaining its current
ownership rights which it secured when it acquired Lucasfilm.
Paramount will continue to be responsible for distribution of the
first four films in the franchise and will receive a financial
participation on any future films that are produced and released.
Though Disney now owns the rights they have not officially
announced that a fifth films is in the works.
Do they keep going with Harrison Ford as an older Indy, or reboot with a young actor, James Bond-style? (Casting off the top of my head: Ryan Gosling. My pal Dave Wiskus says Bradley Cooper.)
