“It’s not just about being a rich kid or anything like that. I approached Donald Trump as what you kind of see in him when you really watch him,” Depp began.

“There’s a pretense. There’s something created about him in the sense of bullydom. But what he is, I believe, is a brat,” the actor quipped to the audience’s cheers.

Depp, who portrayed the business tycoon in a Funny or Die biopic based on Trump’s book, The Art of the Deal, went on to mimic Trump’s way of speaking: “Also the absurdity of where his sentences might travel. … Reagan back in the day, ‘Mr. Gorbachev, tear down that wall!’ Donald Trump, ‘I’m going to build a wall.”

“I’m going to build a wall. A fabulous wall. Sensational. Sensational. And all of my billions are not going to have to pay for it. Because you know why? Mexico is going to pay for it,’” Johnny Depp said in his best Trump voice.

The actor was referring to a Trump’s previous statement about building a wall along the Mexico-US border – funded by the Mexican government – to solve the illegal immigration problem.

Johnny Depp is one of the many celebrities who have criticized Trump for his controversial remarks on Muslims, immigration, and terrorism. Just recently, the billionaire was compared to the German dictator, Adolf Hitler after asking voters to raise their right hands as a sign of their support to him, which reminded people of the Nazi “Heil Hitler” salute.
