Will Smith: American people will "make the right choices" in the country's presidential election

The Suicide Squad star says there are certain things "people shouldn't say or do" when asked about Donald Trump.

Will Smith has told Sky News he is confident the American people will "make the right choices" in the country's presidential election despite controversy over the candidates.

The movie star was speaking as his new movie, Suicide Squad, premiered in London's Leicester Square.

In it, he is part of an anti-hero crew hired to execute a dangerous black ops mission.

Smith told Sky News that his character, Deadshot, has "no rules … can literally say or do anything … no moral bounds".

Asked by Sky's Katie Spencer whether the moral murkiness of the movie's plot was currently being mirrored by aspects of his country's politics, he said: "I don't think it's morally murky, it's morally very clear.

"There is no murk whatsoever.

"There are certain things that in terms of humanity and human rights and just common human decency that people shouldn't say or do.

"There are people in America that are saying and doing a lot of things that are quite embarrassing.

"But I feel very confident that the American people, as we have done in history, will make the right choices."

Smith's comments came in response to a question from Spencer about Donald Trump, who is facing public criticism from within his own party.

In April, Tom Hanks told Sky News: "I think that man will be president right about the time when spaceships come down filled with dinosaurs in red capes."
