9. It Isn't Setting Up A New Franchise - Indiana Jones 5
The currently-shooting fifth Indiana Jones film is widely expected to be the last one to star Harrison Ford, who turned 79 years of age during filming.
However, there is also the understandable expectation among many fans that the film will have Indy pass the torch to a younger successor, allowing the series to continue without him.
With Shia LaBeouf not returning to play Indy's son Mutt, the most obvious choice to become the new Indy is Phoebe Waller-Bridge's new character, who rumours indicate will be one of Indy's former students.
However, you might've missed that producer Kathleen Kennedy confirmed late last year that the new Indy film will be the "fifth and final" entry into the series.
While this doesn't preclude the possibility of Indiana Jones getting a remake or reboot 10 or 20 years from now, Kennedy's language seems to imply that Indy 5 won't be teasing any future films with a new character.
Given how sacrosanct the IP is regarded by fans, it's probably for the best if they get some hopefully-dignified closure when Indy 5 releases next summer.
