I've found the perfect actor to play Donald Trump in the movies that will eventually be made. It's Shane Cortese, a New Zealand actor who played -- appropriately -- the god Loki in the TV series The Almighty Johnsons.
He can play this happy egotist so well, and he looks like him, too. He makes a lot of the same expressions Trump does, in the role of Loki. He dances around when he's set fire to someone's house, never misses a chance to insult people, is rich and powerful, and tricky.
Unfortunately this actor would make Trump even more popular, so I hope it's a long while before someone makes a (or another, maybe there's some I'm unaware of) Trump movie.
