I watched Raiders of the Lost Ark.
I think it's time to re-cast Indiana Jones and make a new movie series set during World War II.
Young Indy is WWI.
Raiders / Last Crusade take place in the late 1930's before the US entered the War in 1941.
Kingdom of the Crystal Skull takes place during the early 1950's I think - I have to check.
They are planning to do Indy 5 with Harrison Ford, which will presumably take place after Crystal Skull and also feature Mutt Williams (Shia LeBouf).
A "new Harrison Ford" should be found (just like with James Bond) and Indy's WWII exploits could be covered. Since he's been all over Europe and Africa for WWI, I think he could serve in the South Pacific versus Japan a little in WWII. It's a possibility to have a different enemy other than the Germans.
Short Round could return as an adult, possibly (though he's Chinese).
I don't know who I'd re-cast as Indy, but he's been played by:
Sean Patrick Flannery
River Phoenix in flashback
They could always keep Jones moving against the Russians in the 1960's with Harrison Ford as well. William Shatner played Kirk in action movies during his character's 50's and 60's.
But we need more Jones!
