John Irvin, the British director best known for his work on “Hamburger Hill” and the “Tinker Tailor Soldier Spy” miniseries, died last week. He was 86.

Irvin’s death, which occurred on Aug. 11, was confirmed by the director’s producers. It’s said the filmmaker passed at his sister-in-law’s home in the U.K. A cause of death was not shared.

Irvin’s multi-decade career boasted over 30 films and three BAFTA nominations. In addition to “Hamburger Hill” and “Tinker Tailor Soldier Spy,” he was known for his work on “Turtle Diary,” “A Month by the Lake,” “City of Industry,” “Ghost Story” and “Widow’s Peak.”

Yet, he is most celebrated for his realistic depiction of warfare in his Vietnam War movie, the aforementioned “Hamburger Hill,” which starred Michael Patrick Boatman, Don Cheadle, Dylan McDermott, Tim Quill, Courtney B. Vance and Steven Weber.

Irvin was born alongside his twin, David, in Newcastle upon Tyne, England’s northernmost city, on May 7, 1940. He later attended the London Film School, graduating in the late ‘50s.

He started out his career by making documentaries in the ‘60s, including a short, titled “Mafia No!,” that was about an Italian activist named Danilo Dolci. “Mafia No!” was notably nominated for a BAFTA Award for Best Short Film.

By the ‘70s, Irvin transitioned into directing for TV, where he helmed 1974’s “Possessions” and “Haunted,” as well as the pilot for “The Nearly Man.” But it was his 1979 miniseries adaptation of John le Carré’s “Tinker Tailor Soldier Spy” which led to international acclaim, as the project was nominated for a BAFTA Award for Best Drama Series and a Primetime Emmy Award for Outstanding Limited Series.

Irvin later made a name for himself in Hollywood by directing a number of pictures across genres, including the 1980 Christopher Walken-led “The Dogs of War” and the 1981 horror film “Ghost Story.”

Other notable credits included “Next of Kin,” “Robin Hood” and “Raw Deal.”

Irvin was predeceased by his wife Sophie, who passed from cancer in 1991. He is survived by their three children and his two grand children.

Yellowstone co-creator Taylor Sheridan has limits on what spinoffs he will do and has shut the door on a fictionalized version based on the Four Sixes Ranch in Texas.

In a new interview, Sheridan said that the previously announced 6666 spinoff was not happening.

“There’s never going to be one,” he said on the Rodeo Time podcast. “I would never fictionalize that ranch.”

He continued, “People thought that that was going to be a thing, but I would never do that.”

Yellowstone fans believed that a spinoff set in the real-life ranch was happening after Jefferson White’s character, Jimmy Hurdstrom, was sent to the 6666 Ranch in Season 4.

“I’ve actually got on my computer all the scenes of Jimmy at the 6666 pulled out and strung together, and it makes its own perfect little movie,” Sheridan said. “You watch him go there as this misfit, and leave as a man and a respected cowboy.”

Sheridan, along with a group of investors, purchased the ranch in 2020 and would not want to “trivialize” the working ranch by “making up lives” and “invent drama.”

“So now I’m trivializing and fictionalizing something where real people work, and they raise their families there, and I could never do that to them,” he added. “I could never do that to the cowboys that dedicated themselves, and everybody that works on that ranch. I’m very protective of the Sixes, and it’s a big responsibility to be the person who has to protect that ranch, so I have to be very, very careful with it.”

In 2022, Paramount announced at its Upfront presentation that it was developing the Yellowstone spinoff, 6666.

The series was set when Comanches still ruled West Texas, and no ranch in America is more steeped in the history of the West than the 6666. Still operating as it did two centuries before, and encompassing an entire county, the 6666 is where the rule of law and the laws of nature merge in a place where the most dangerous thing one does is the next thing. The 6666 is synonymous with the merciless endeavor to raise the finest horses and livestock in the world, and ultimately where world-class cowboys are born and made.

Sheridan, John Linson, Art Linson, David Glasser, Ron Burkle, and Bob Yari were signed up as executive producers, with 101 Studios and MTV Entertainment Studios producing.

Although the 6666 spinoff did not materialize, Yellowstone has plenty of other stories in its universe. In 2021, 1883 premiered, followed by 1923 in 2022. Marshals premiered earlier this year, and Texas-set Dutton Ranch followed soon after.
