Actor looks unrecognizable as he shows off slimmed-down frame on set of new movie

Jonah Hill? Is that you?

The 41-year-old actor looked unrecognizable while shooting scenes for his forthcoming movie, “Cut Off.”

Hill, who was photographed alongside co-star Kristen Wiig, showed off his strikingly slimmed-down frame as he stepped out of and into his trailer in character.

The “Superbad” star wore a tight leopard-print turtleneck tucked into low-rise skinny jeans adorned with long black fringe. His black belt accentuated his tiny waist.

Hill, who also wrote and is directing the comedy, completed his ’70s-inspired look with a shaggy blond wig and thick-rimmed glasses.

He carried various beverages and reviewed his script in between takes.

Wiig, 52, was also dressed the part, as the actress was snapped wearing a teal lace bra atop a purple lace shirt tucked into red lace leggings.

She accessorized her eccentric ensemble with a light pink skirt and a black belt.

While Hill’s weight has fluctuated in the past, he has seemingly been able to maintain a svelte body for about a decade.

The “21 Jump Street” star first slimmed down dramatically in 2011, losing 40 pounds with the help of a nutritionist and a Japanese diet.

By the fall of 2014, he had regained quite a bit of weight, which Page Six reported was the result of binge eating.

“He’s in a bad place, which is just making the cycle worse,” sources told us at the time.

The actor continued to put on pounds through the following spring but began slimming down again two years later.

He lost even more weight and showed off his thin frame the following summer; he was even thinner by the winter.

Hill addressed his weight fluctuation in a 2018 interview with Ellen DeGeneres, saying he had “spent most of [his] young adult life listening to people say that [he] was fat and gross and unattractive.”

He added, “I really believe everyone has a snapshot of themselves from a time when they were young that they’re ashamed of. For me, it’s that 14-year-old overweight and unattractive kid who felt ugly to the world, who listened to hip-hop and who wanted so badly to be accepted by this community of skaters.”

While he was still “under construction” at the time, Hill confessed that he was starting to understand the concept of self-love.

The “Wolf of Wall Street” star appears to have lost even more weight since then and currently looks to be the skinniest he has ever been.
