Days after reaching a plea deal with federal prosecutors on his unpaid taxes and a felony gun charge in 2023, Hunter Biden appeared panicked and short-tempered, according to leaked footage from a new documentary about the former first son seen by The Post.

“What are you talking about ‘I’m protected?” wide-eyed Biden animatedly says into a cell phone in the footage, from the documentary-in-progress being made by Hollywood writer and lawyer Kevin Morris, who loaned Biden more than $6.5 million for personal expenses and back taxes.

Morris, a novelist and producer known for brokering deals for “South Park” and “The Book of Mormon,” had been trailing Biden with a film crew between 2021 and 2024, during his father Joe Biden’s White House term. He also documented the scandal-scarred ex-lobbyist’s foray into the art world.

In addition to recording the self-taught artist’s gallery openings in Los Angeles and New York, Morris was seen directing a film crew taping Hunter Biden outside courthouses where Biden appeared on tax evasion and the gun charge.

Morris even took his cameras to Serbia, where his crew was accused of crashing the set where filmmaker Phelim McAleer was shooting “My Son Hunter,” a flick mocking the Biden family that was distributed by Breitbart in September 2022.

The footage seen by The Post is time-stamped June 29, 2023, nine days after Biden’s attorneys made the plea deal.

“Who am I protected by, Georges? Who am I protected by?” Hunter yells into the cellphone in what appears to be his Malibu art studio. Biden, 56, appears to be speaking to his former New York City-based art dealer.

The video clip also shows Berges contemplating a new work by Biden, who appears with the end of a paintbrush in his mouth and holding his toddler son Beau on one hip.

After contemplating the artwork for a moment Berges politely asks: “You’re still working on this?” in a courtyard of what appears to be BIden’s home, where canvases are leaned up against walls and spread on the floor. “I think it’s missing something.”

The footage then cuts to various press clips of the controversy surrounding the sale of Hunter’s work while his father was president of the United States. One clip features Republican lawmakers urging former Attorney General Merrick Garland to appoint a special counsel to investigate Biden’s art sales.

“There’s something special about his art,” Berges says in the documentary. “I think it’s my job to tell that story.”

Berges, who was hauled before a House committee investigating Biden’s art work, ended his contract with the former first son in September, 2023, shortly after the filming.

Berges did not return a request for comment Monday.

Under the terms of the plea deal, made with Delaware prosecutors, Biden would only receive two years probation instead of jail time on the gun charge and plead guilty to two misdemeanors for his failure to pay tax on more than $1.2 million in income for 2017 and 2018.

The deal fell apart a month later, in July 2023 when Judge Maryellen Noreika questioned the unusual structure of the deal.

Hunter was later pardoned by his father in 2024, shortly before Joe Biden left office. He has not repaid his debts to Morris, according to sources, and currently owes a total of $20 million, much of that to his former lawyers, according to reports.

Last month, The Post reported Biden is currently living in California, at a luxury ranch owned by Joe Kiani, one of his father’s former billionaire benefactors, although he claims he divides his time between the US and South Africa.

It’s not clear when the documentary film will be released. Morris did not return a request for comment Monday. Hunter Biden’s attorney declined to comment Monday.
