Director Uwe Boll went on an expletive-laden rant on Sunday after his new film struggled to reach its crowdfunding goal on Kickstarter.

He also blasted Hollywood stars like Brad Pitt, Angelina Jolie and Robert Downey Jr., who are “laughing” at low-income families who pay to see their “Marvel Avengers bulls–t dirt.”

“Basically my message is ‘f–k yourself’,” the German filmmaker told movie fans. Boll also ridiculed the staff at Kickstarter, who he said manipulated him into thinking his new movie, “Rampage 3: No Mercy,” could raise $55,000 in a month.

The sequel to “Rampage,” his 2009 film, has only raised $24,500 with three days left. It’s the third failed attempt to reach the target goal after efforts on similar sites like Indiegogo.

“What retarded amateur idiots collecting money on that website,” he said of Kickstarter. “For me crowd funding is absolutely dead.”

“I have enough money to play golf until I’m dead,” he added.

Boll is well-known in the film blogosphere for his temper. In 2006, he famously challenged movie critics to fight him in the boxing ring. Footage from the matches was used on the DVD extras of his horror pic “Postal.” He also invited directors Quentin Tarantino and Roger Avary to step into the ring. Both filmmakers declined.

In one of the two videos posted on Sunday, Boll also blasted Hollywood’s newest investors in countries like China and India: “I’ll find another Chinese, Alibaba idiot…who wants to see his f—king yacht in Cannes to f–k supermodels. That is the movie business!”

“Iron Man does not exist. Captain America does not exist,” he said. “Wake the f–k up!”
