Anonymous Content produced a series of non-partisan interviews with various celebrities for the #VoteYourFuture campaign, and did not include De Niro's contribution because of its partisan content.
De Niro, who has been vocal about his disdain for the Republican presidential nominee, hurled a litany of insults at Trump, echoing Colin Powell's statements that Trump is "a national disaster."
"He's so blatantly stupid," De Niro said. "He's a punk. He's a dog. He's a pig. He's a con."
"He talks about how he wants to punch people in the face?" De Niro added. "Well I'd like to punch him in the face. This is someone we want for president? I don't think so."
He ended the rant by encouraging people to cast their vote.
"If you care about your future, vote for it," he said.
