Tom Hanks doesn't have great things to say about Donald Trump, I think we can all agree on that.

And as for Trump's chances of pitching up camp in the White House, the Forrest Gump actor does not foresee the controversial Republican winning the election.

Speaking at the London premiere of his new film, 'A Hologram For The King,' Hanks said:

"I think that man will be president right about the time when spaceships come down filled with dinosaurs in red capes."

On Trump's presidential slogan, he said:

"Here's the problem. America's already great so I don't know what he is talking about."

Hanks is firmly placing his support in Hillary Clinton's camp.
