Donald Trump is the real-life Lex Luthor and a “dangerous buffoon,” according to a 25-year-old documentary that was only recently released.

“Trump: What’s the Deal?” can currently be viewed in its entirety on YouTube, and producers created a new trailer with footage from his unfolding presidential campaign to capitalize on public interest.

“Everyone knows Trump is a buffoon, but few realize how dangerous a buffoon he really is,” the narrator says. “But now a long-suppressed investigative documentary is about to emerge just in time to drag the skeletons from Donald’s many, many closets — from mob connections to family connections.”

So why wasn’t this film released?

According to the film’s opening, which is set to the tune of Frank Sinatra’s famous “New York, New York,”the real estate mogul “screamed and shouted and threatened lawsuits.”

It’s hard to imagine he won’t be screaming and shouting — or at least tweeting — about the documentary surfacing online for voters to watch free of charge.

“Now that Trump is running for president, it’s time for the American people to meet the real Donald and learn how he does business,” the narrator says. “The old Trump and the new Trump? They’re the same Trump.”

Another fun fact about Trump that the documentary highlights is how he “pissed off Superman.”

“It’s the American dream gone bazerk,” late actor Christopher Reeves says on camera. “If your dreams step on the lives of ordinary people and ruin the quality of their life and their neighborhood, they have to be stopped.”
