Well, so much for a proper finale from the original team.
Variety reports that Spielberg has stepped down as director for the first time in this series' history. He is relinquishing Indiana Jones 5 of his own volition "in a desire to pass along Indy’s whip to a new generation to bring their perspective to the story." He will remain as a "hands-on producer," while James Mangold of Ford v Ferrari "fame" is said to be in talks as his replacement in the director's chair. Ford is reported to still be starring, but I wasn't born yesterday.
And just like that, the official ending of the Spielberg era of Indiana Jones becomes Shia LaBeouf shuffling out of a chapel.
