A new public service announcement featuring likenesses of celebrities including Michael Douglas, Chris Rock and Amy Schumer to warn voters about AI deepfakes, including those that could be unleashed on Election Day to try to suppress the vote.

The spot is from RepresentUS, a nonpartisan anti-corruption organization that includes figures like Ed Helms and Jennifer Lawrence on its board.

The central aim of the spot is to warn voters of messages that seek to dissuade people from voting. Before the New Hampshire primary, a robocall deepfake of Joe Biden’s voice was sent to voters that tried to discourage them from casting a ballot.

Others likenesses featured in the spot include Laura Dern and Orlando Bloom, while the real Rosario Dawson and Jonathan Scott appear at the end.

According to RepresentUS, the likenesses of the celebrities were used with permission.
