NEW YORK (AFP) - Some of America's biggest stars - including actors Robert Downey Jr and Scarlett Johansson - appear in a short video unveiled Wednesday (Sept 20), taking potshots at Republican presidential candidate Donald Trump while rallying voters to the polls on election day.

"On Tuesday, November 8, this country will make one of the most important decisions in its history," the film and stage actors say as part of the effort launched by Save The Day, a Super PAC supporting Hillary Clinton.

PACs, or political action committees, are organisations created to raise funds to support or oppose a given candidate or political cause.

Super PACs can raise even larger amounts of cash during the immensely expensive American political campaigns, but are forbidden from making direct contributions to a candidate.

Leslie Odom Jr, who until recently a star of the hit play Hamilton, makes a reference to  Mr Trump in the three-minute video.

"Do we really want to give nuclear weapons to a man whose signature move is firing things?" Odom asks.

Likewise, Hollywood star Don Cheadle appears to allude to the Republican presidential nominee when referring in the video to "a racist, abusive coward who could permanently damage the fabric of our society".

Save The Day was founded by Joss Whedon, director of two installments of the hit The Avengers films, among other works.

The get-out-the-vote video was unveiled less than seven weeks before the Nov 8 presidential election.
