Yes!!!!
He already was recast! Anybody remember River Phoenix, Sean or Patrick Flannery, et al?
This may sound insane, but what about Luke Wilson? I think he looks a little like a young Ford, and he's a pretty good actor. We all know he can pull off the comedic aspects of the character, as well as the serious ones. I say make at least two more films after this next one, and have them be set in the early 1940's, showing some post-LC and pre-KOTCS adventures. That way, we can have a return to the pulpy, serial, nazi-fighting feel of the originals, and we could have six solid IJ films to compliment the STAR WARS series.
Make any more IJ films preqels or interquels, so we can have one solid contnuity rather than a fresh reboot.
Honestly, IMHO recasting Indiana Jones and setting furture films in the 30's and 40's, is a MUCH better idea than continuing the series with Shia Labouf as the
new "Indy".
