Years ago, 2008 in fact, Oliver Stone directed a movie about George W. Bush, W starred Josh Brolin as the titular character. Now in 2021, I think it’s time someone made a movie about President Trump, although funding might be an issue, I think Oliver Stone could be one of the few directors with balls to do it.
However it would need the right actor for the role.
Suggestion #1 here is Jon Voight. Voight is an incredible actor, or great versatility and range. He’s also in the correct age bracket, understands The President and, y’know, could fit right in with little more than a bit of hair dye. Both men are also around the same height, standing at a manly and towering 6’3.
