“Marissa is more socially wealthy”: Sarah Snook points out differences between her Succession and All Her Fault characters

Sarah Snook is back on television with All Her Fault. The Peacock mystery thriller marks the actress' first television project since the conclusion of HBO’s hit show Succession, in which she starred as Shiv Roy.

In the new series, Sarah plays Marissa Irvine, a mother who goes to pick up her young son from a playdate but is shocked to find out that the woman who opens the door has never heard of him.

As Sarah has returned to the screens after two years, and again plays a rich character, fans are comparing Marissa with Shiv. The actress, however, has said that the two are pretty different, despite both being wealthy. She said in an interview with Variety:

“[They are similar] only in the sense of like that they’re wealthy characters. I think Shiv is in a different category. She’s in this astronomical wealth elite, whereas Marissa is more socially wealthy, and you might meet her on the street. You wouldn’t meet Shiv on the street.”

Sarah Snook reveals how Marissa Irvine in All Her Fault differs from Succession’s Shiv Roy

Talking about which character is relatable to her, Sarah Snook revealed that she connects with Marissa Irvine from All Her Fault more, as she is a warm person. On the other hand, Shiv Roy is a cold-hearted woman who went to great lengths to seek control over the family business. Sarah said:

“I think Marissa is more of a reflection of myself, maybe — much more personable, warm. Whereas Shiv is much more of a cold-hearted bitch. She’s a different kind of stern character.”

In All Her Fault, Sarah plays a wealth manager who is on a mission to find her missing son. Though the series is a mystery thriller, it also highlight themes like patriarchy and societal pressures on working mothers. The show premiered on Peacock on November 6, 2025, and Sarah has earned positive reviews for her performance.

Apart from Sarah, All Her Fault stars Jake Lacy as Peter Irvine, Abby Elliott as Lia Irvine, Daniel Monks as Brian Irvine, Jay Ellis as Colin Dobbs, Sophia Lillis as Carrie Finch, Duke McCloud as Milo Irvine, Michael Peña as Detective Alcaras, and Dakota Fanning as Jenny Kaminski.

Sarah shot to global fame and acclaim with Succession. Created by Jesse Armstrong, the series revolved around the Roy family, which owned Waystar RoyCo., a media conglomerate. After the patriarch and head of the business, Logan, started facing health issues, his four children entered into a struggle to lead the company.

Sarah played Logan’s youngest child and only daughter, Shiv. The character became a fan favorite due to her determined attitude and competency. Her troubled marriage with Waystar executive Tom Wambsgans also became a highlight of the series. During her interview, Sarah talked about where she thinks Shiv would be following the conclusion of Succession and said:

“I think Jesse Armstrong, the creator, put it really well when he said at one point, “I don’t really believe that people can change. They’re always going to be who they are, inevitably.” There’s an inevitability, I think, about people.”

She added:

“And there’s something about that with Shiv, like she probably is still second next to Tom. In some ways, still in charge, and in some ways, scratching, scrapping, reaching for — but always just missing out. And that’ll always be the source of great frustration and annoyance for her.”

All episodes of All Her Fault are streaming on Peacock.
