Robert de Niro gives Donald Trump both barrels in a new video posted online.

The movie legend uses almost every insult there is to blast the GOP presidential nominee for a celebrity “Get Out The Vote” commercial.

“He’s so blatantly stupid,” de Niro says of Trump in the clip, which has already garnered more than half a million views on Facebook.

“He’s a punk, he’s a dog, he’s a pig, he’s a con, a bullshit artist,” he adds. “A mutt who doesn’t know what he’s talking about, doesn’t do his homework, doesn’t care, thinks he’s gaming society, doesn’t pay his taxes.”

De Niro also said he’d like to punch the brash businessman in the face.

In August, the “Taxi Driver” star said it was “crazy” that some Americans were supporting Trump. “He shouldn’t even be where he is, so God help us,” he told an audience at the Sarajevo Film Festival.

Check out de Niro’s straight-talking monologue in the clip above.

Editor’s note: Donald Trump regularly incites political violence and is a serial liar, rampant xenophobe, racist, misogynist and birther who has repeatedly pledged to ban all Muslims — 1.6 billion members of an entire religion — from entering the U.S.
