Indy IV Should Have Been Like This...
Released in about the mid 1990s when Harrison still looked young. It should have had Henry Jones Senior (Sean Connery) and Sala in it. Marion could have still returned, or it would have been a new female sidekick and the villans would have been the Nazi's again. Finally, the story should have been something like Indiana Jones and the Fate of Atlantis. It could have still been set in the 1950s, but it would have been about Nazis who were alive in South America after the war who were looking for Atlantis. That's what I would have done.
