Successor Sarah Snook reveals co-star Brian Cox would fly into a 'diabetic rage' on set

Successor Sarah Snook has revealed that co-star Brian Cox sometimes flew into a “diabetic rage” on set.

The actress, 36, is best known for her starring role as Shiv Roy in the HBO drama that follows the Roy family's struggle for control of a global business empire.

Speaking to Times Radio, Sarah said 77-year-old actor Brian, who played Logan Roy, had a 'habit' of falling into a 'diabetic rage'.

She explained: 'He has a habit of going all out sometimes – or it could be real, who knows? – diabetic rage where he suddenly goes and, I think part of it is a little bit, a little bit trying to shock the energy of the set and, like, you know, ruffle a few feathers, to get it going to get , get started and go faster.

'Yes. Because the quality of his voice can sometimes be very frightening. Certainly. Thunderous.'

Speaking about the impact of the HBO series, she said there is “fear” of being “limited” by Shiv Roy's role.

She said: 'When you're known for a certain role – more internationally – there's a fear, I think, as an actor that you're going to be limited to those types of roles and the things that came in during the time I was playing. the shooting of Joe tended to be of a Shiv nature.

'And for me personally, that's so far removed from who I am as a person, and not that I wanted to play myself. And I certainly don't get the chance to do that very often in Dorian Gray – 26 versions of myself. But I wanted to be able to stretch my wings a little bit and say, there's something more around here.'

It follows a hugely successful awards season for Snook, whose role in Succession saw her triumph at the Critics Choice, Golden Globes and Emmy Awards.

However, in an interview with The Sunday Times, Snook revealed that her path to superstardom and landing the role of Shiv Roy was anything but glamorous.

She described herself as “extremely depressed” as a teenager growing up in Sydney and putting herself through drama school because her parents were broke.

Snook attended the prestigious National Institute of Dramatic Art in Sydney and recalled how people during lectures would make fun of her falling asleep because she had no energy because she couldn't afford nutritious meals.

Sharing how she lived on white rice, she explained: “I was making $120 a week, the rent was $90 and $12 went to my phone. It was definitely character building.”

“No wonder I fell asleep in history theater classes,” she recalled. 'I always fell asleep in the back row.

'I raised my blood sugar and didn't eat protein, I couldn't afford it. People would bet on whether I would fall asleep.'

Snook felt “lost” after graduating in 2008 and started working at a cafe to make ends meet. The actress said she was down to her last A$10 before the acting work started rolling in.

She played several small roles in Australian films that won her awards and slowly made her way to becoming an established actress in 2015.

Snook played Apple entrepreneur Andrea Cunningham in the Hollywood biopic, making her West End debut alongside Ralph Fiennes.

When she was offered the role of Shiv, the actress admitted that she didn't understand the appeal of a family of brats who were only interested in increasing their bank balance.

She said her friends questioned the character and assured them, “That was my reaction too!”

However, as the series progressed, Snook confessed that she had no choice but to root for Shiv, hoping that she would be the one to become CEO.

Now the movie star has more wealth than she ever imagined. It was reported that she earned £300,000 per episode during series three.

But she insists she is fully aware that it could all disappear tomorrow and she has made peace with the prospect that she could one day be penniless again.

She took home the Best Actress in TV Series Drama statuette at the Golden Globes for her portrayal of political strategist and media heir Siobhan 'Shiv' Roy.

She defeated Emma Stone (The Curse), Imelda Staunton (The Crown), Helen Mirren (1923), Kerri Russell (The Diplomat) and Bella Ramsey (The Last of Us).

“This show changed my life,” Snook said in her acceptance speech, before thanking her fellow cast and crew.

“This was a team effort, that was always what made the show great.”

At the Emmys, Snook took home the award for Outstanding Lead Actress.

She once again faced tough competition, including: Sharon Horgan – Bad Sisters, Melanie Lynskey – Yellowjackets, Elisabeth Moss – The Handmaid's Tale, Bella Ramsey – The Last of Us and Keri Russell – The Diplomat.

During her emotional acceptance speech, she said, “Wow. Thanks to everyone who voted and enjoyed the show as much as we did as the cast and crew who made it.

'We did everything we could and the bar was so high. I think that's why we gave our best from every department, led by Jesse and Mark and my cast, who I love so much and will miss.”
