Billy Bob Thornton, 70, appeared at the Newport Beach TV Fest looking dramatically younger , sporting a blond cropped haircut that mirrors his character Tommy Norris in the serries Landman. While on a panel discussing the show’s upcoming third season, he opened up about his rare AB‑negative blood type, a highly restrictive diet, and dispelled rumors about a viral nude scene.

Thornton's blond crop mirrors Landman's Tommy Norris

During the Saturday panel at Newport’s Lido Theater, Thornton arrived in a black vest under a silk waistcoat, his hair dyed blond and cut short to echo the bleached look of Tommy Norris, the outlaw he portrays in Landman. The visual cue was intentional, according to the actor,and generated buzz among fans who noted the striking similarity.

AB‑negative blood type forces Thornton into a meat‑free, dairy‑free diet

In a recent interview on Howie Mandel’s podcast, Thornton explained that his rare AB‑negative blood type limits his digestive enzymes, compelling him to avoid wheat, dairy, pork, beef and other meats. He said, "It means you have less digestive enzymes," and described a lifelong pattern of allergies and post‑meal illness that he only linked to his blood type in the late 1980s.

The claim aligns with naturopathic theories from Peter J. D’Adamo, who suggests AB individuals should steer clear of caffeine,alcohol and cured meats, though scientific consensus on blood‑type diets remains weak. As the report notes, “there is no strong scientific consensus supporting blood‑type‑specific diets.”

Landman’s third season teased amid viral nude‑scene controversy

Thornton and co‑star Ali Larter fielded questions about the upcoming third series, while producers reminded audiences that the infamous full‑frontal nude moment from season two was achieved with prosthetics, not actual nudity. co‑creator Christian Wallace clarified to The Hollywood Reporter that the scene’s artifice surprised even the crew.

Thornton reflects on turning 70 and gratitude

On CBS News’ Sunday Morning in November 2025, Thornton admitted feeling “trepidation” about reaching 70, describing it as a milestone that required “a few meetings with myself late at night.” He now emphasizes a sense of blessing, saying, "Every day when I wake up I just say I’m blessed. that's really it."

Is the blood‑type diet scientifically valid?

The podcast interview left two key questions unanswered: whether Thornton’s digestive issues are truly caused by his AB‑negative status, and if his restrictive regimen offers measurable health benefits. Neither the actor nor medical experts provided concrete data, leaving the claim open to further scrutiny.
