She famously gained almost 30lbs to play Bridget Jones for the 2001 romantic comedy – and even said in an interview that the continued yo-yo dieting for the film series had lead to panic attacks.
But for her latest transformational role, Renee Zellweger is getting a little prosthetic help.
On Monday, the Oscar-winner was pictured wearing what is commonly referred to as a ‘fat suit’ as she filmed a new true crime drama for NBC titled The Thing About Pam in New Orleans, where she plays convicted killer Pam Hupp.

Sporting a large bodysuit-like undergarment, that was also later pictured being carried by a wardrobe assistant, the 52-year-old was able to transform from her slim physique to a much bigger frame to play the role of Hupp.

Zellweger also appeared to have a prosthetic nose as she was seen heavily made-up to resemble the criminal.
In July this year, Hupp – who is already serving a life sentence for shooting a disabled man dead – plead not guilty to the 2011 murder of her friend Elizabeth ‘Betsy’ Faria, after they were stabbed 55 times.
Prosecutors have alleged that Hupp killed Faria four days after persuading her to switch a $150,000 life insurance policy to her, and was accused of trying to frame Faria’s husband Russell.
Zellweger was seen sipping on an extra-large soda and was dressed down in jeans and a large winter jacket as production on the six-episode series rolled on, which is being co-produced by the star’s own production company, Big Picture Co.
The use of a ‘fat suit’ in Hollywood has become a controversial option for actors recently, with both Gwyneth Paltrow and Sarah Paulson saying they regret wearing one for their respective roles, amid cries of fat-phobia.
Last year, Paltrow admitted her regret over the choice to wear one in the movie Shallow Hall, calling it a ‘disaster’ and felt ‘humiliated’ when wearing it in public.
Whereas Paulson, 46, caught controversy for wearing the device on the FX series Impeachment: American Crime Story, leading to an apology from the actress.

‘There’s a lot of controversy around actors and fat suits, and I think that controversy is a legitimate one,’ she told the Los Angeles Times. ‘I think fat phobia is real. I think to pretend otherwise causes further harm.’
However, Zellweger – who is known for her ultra-slim frame in Hollywood – decided against using a fatsuit for her Oscar-nominated turn as Bridget Jones on 2001, though she admitted the transformation left her feeling ‘whacked.’
The slender actress famously embarked on a 4,000 calorie-a-day diet to load on 20lbs in just a few months to play Bridget Jones (twice) — then, as swiftly as she gained the curves, her weight plummeted to a sinewy size zero.

In 2007, she addressed the health implications of her yo-yo dieting for the role, admitting: ‘Can I just tell you my body is whacked by the time we finish one of those.’
‘It doesn’t know what has happened because it thinks there’s supposed to be a baby and there’s no christening.’
She added: ‘Did you see that movie about fast food, Supersize Me? I had a panic attack with all the specialists talking about how bad this is for you, long term, putting on that much weight in short periods of time and they’re all saying, “You must stop this now or you’re going to die’.”
‘It sounds like heaven,’ Zellweger said about putting on weight for the film to play Bridget. ‘For two days it’s bliss and then you’re full, OK? And you can then indulge all your fantasies about over-eating.’

‘Fantasies about non-stop chocolate consumption or your fantasies about ordering the pizza and the spaghetti and the garlic bread.
‘Then after a week your glucose levels are going crazy. You’re up and down and all over the place. It doesn’t feel good, and no one wants to hear that, but it’s the truth.’
By the time of the third outing of the film – Bridget Jones’s Baby in 2016 – Zellweger said in interviews that director Sharon Maguire wanted Bridget to be in a place in life where she had achieved her ‘ideal weight.’
‘I put on a few pounds. I also put on some breasts and a baby bump,’ she told Vogue at the time, adding that ‘Bridget is a perfectly normal weight and I’ve never understood why it matters so much. No male actor would get such scrutiny if he did the same thing for a role.’
Her most impressive transformation yet? Renee could be taking her acting skills to new heights on the crime drama
Meanwhile, her latest role is far more grisly subject matter compared to Helen Fielding’s fictional romantic.
62-year-old Hupp is charged with first-degree murder and armed criminal action for her friend Faria’s slaying back on December 27 2011.
Hupp was sentenced to life without the possibility for parole in 2019 for luring Louis Gumpenberger, 33, to her home claiming to be a producer for Dateline before shooting him dead in an elaborate plot to divert attention from herself in the Faria case.
Speculation has also swirled that she was responsible for her own mother’s fatal fall in 2013.
