On Monday evening, she will be making an appearance on The Tonight Show Starring Jimmy Fallon to talk about her new show The New Look.

In the biopic series, she will portray Catherine Dior, Christian Dior’s sister.

The show tells the story of how Dior, Coco Chanel, Pierre Balmain and Cristóbal Balenciaga navigated the horrors of World War II and launched modern fashion.

In 1941, Catherine Dior joined the Resistance before later being arrested by the Nazis and being imprisoned at the Ravensbrück concentration camp.

For the role, Williams explained in a Harper’s Bazaar U.K. cover interview that she lost 26 pounds by going through a difficult regimen.

She said she was carefully overseen by medical professionals as she drastically cut her food intake.

The actress also explained she lost most of her weight through sweating besides eating very little.

‘I had to be up at 4 a.m. to start sweating,’ she said, detailing what a day of preparation for filming was for her.

‘The night before, at about 7 or 8 p.m. I was allowed to have something salty and dehydrating — some smoked salmon and a tiny glass of wine.

‘Then I had a boiling-hot bath with lots of salts in it,’ she continued. ‘And I sort of levitated to bed and slept for maybe three hours and woke up and had a handful of nuts.’

Because she was eating so little, however, she said she was struggling to get any rest.

‘I wouldn’t be able to sleep through the night at this point,’ she added.
