The actor was dressed in sixties inspired clothes and wore a sandy haired wigCredit: BackGridThe movie star in question is Jonah Hill, who looked very different following his dramatic weight loss.
The 21 Jump Street actor showed off a slimmer physique as he filmed his latest picture.
Jonah was in full costume which saw him wearing a sandy haired wig.
He had grown out his beard and he wore sixties inspired clothes.
The actor was seen reading a script as he left his trailer to start filming new movie Cut Off.
Jonah was also spotted on set with his co-star, Kristen Wiig.
But it was the actor’s dramatic wight loss that was really noticeable on the film set in Los Angeles.
Jonah has seen his weight fluctuate over the years, and the star – who suffers from anxiety attacks – admitted being overweight as a child “f****d him up”.
“When I was a kid, exercise and diet was framed to me as like, ‘There’s something wrong with how you look,'” he said in Netflix documentary Stutz,
“But never once was exercise and diet propositioned to me in terms of mental health. I just wish that was presented to people differently.”
Jonah said inside he still feels like “a 14-year-old boy who’s very overweight and has acne and feels very undesirable to the world.”
“Inherently, at my core, I’m still this unlovable person,” he added.
“But the work is inching toward [realising] that it’s great to be this person. But that’s still very hard.”
Jonah first landed on our screens in the comedy films Accepted in 2006, and Superbad in 2007.

Jonah has impressed fans with his weight loss over the last few yearsCredit: GettyHe said his 21 Jump Street co-star Channing Tatum encouraged him to hire a nutritionist and personal trainer in 2011.
“I called Channing Tatum and said, ‘Hey, if I ate less and go to a trainer, will I get in better shape?'” Jonah shared on The Tonight Show in August 2016.
“And he said, ‘Yes, you dumb motherf–er, of course you will. It’s the simplest thing in the entire world.”
He managed to shed an impressive 40lbs, but he piled it back on while staring in The Wolf of Wall Street in 2013.
Following the release of War Dogs in 2016 Jonah slimmed down again and has managed to stay in shape ever since.
