In real life, Aussie actress Kat Stewart is a down-to-earth mum-of-two, humble, curious and self-aware. Julie Cosgrove, the character she plays in season two of Black Snow, couldnโt be more dissimilar.
โPart of the fun of being an actor is walking around in someone elseโs shoes,โ Kat, 52, tells TV WEEK. โJulie was different to me. She thinks sheโs the most important person in the room at all times. Thatโs not how I carry myself.โ

โJulie doesnโt suffer from imposter syndrome, which we women are most guilty of โ weโve got to stop!โ
The six-part second season of Black Snow reinvestigates the cold case of a missing young woman โ Zoe Jacobs (Jana McKinnon) โ who โran awayโ from her own 21st birthday party in the picturesque town of Moorevale in Queensland in 2003.
Zoe left behind a note telling her parents she needed time to follow her own path, but was never seen again. While her mother believes sheโs built a new life for herself somewhere far away, her father thinks his daughter has met a more sinister fate.
Julie is the mother of Zoeโs ex-boyfriend and is a senator involved in shady deals that took place at the time Zoe went missing. When the detective heading the case โ James Cormack, played by Vikings and Boy Swallows Universe star Travis Fimmel โ tries to expose her, she needs to silence him.
Despite her co-starโs impressive rรฉsumรฉ, Kat wasnโt intimidated.

โSomeone else asked, โWere you daunted [working alongside Travis]?โโ she recalls. โIf Iโd thought about it, probably. But luckily, I didnโt [find it daunting] โ actually, I found it really useful. I thought the first series was brilliantly executed, and the performances were amazing, so it was great to have that as a reference to know something about the production values.โ
Kat has had an inspiring career herself, starring in hit series such as Underbelly, Offspring and Five Bedrooms, a surprise to her considering the โhuge unemployment rateโ for actors in Australia.
โThere are never enough roles at any age,โ she says. โIโve been very fortunate. Things are much better than they were in terms of seeing characters beyond the age of 30. It used to be that you fell off a cliff.โ
Something that did affect her career was having her children โ Archie, 12, and eight-year-old Georgia โ which she was inspired to do after a storyline in Offspring made her realise, at age 38, that her biological clock was ticking.
โIโm so grateful for Offspring for reminding me that I didnโt have forever, because I was distracted,โ she says. โMy kids are my two favourite people, but it does affect your career. I probably would have worked more interstate, done more theatre.

โIโm reluctant to espouse all the wonderful things about motherhood โ because itโs not for everyone and itโs not possible for everyone โ but Iโm very grateful for my two kids, because theyโre really cool.โ
Kat fell in love with theatre when she was about eight and now performs in plays alongside husband and fellow actor David Whiteley.
โWeโre going to the Sydney Theatre Company next year with Whoโs Afraid Of Virginia Woolf,โ Kat reveals. โWe play George and Martha, a couple ripping each other to shreds. Itโs a really vicious play. We love working together.โ

Kat doesnโt regard herself as a Method actor, although there are small things she picks up after sheโs developed a relationship with a character.
โOne thing Iโve noticed over the years is my wardrobe often gets influenced by the character for a while,โ she says. โAnd Roberta Williams [the wife of underworld figure Carl Williams, who she played in Underbelly) comes out in bad traffic.โ
Roberta earned Kat a TV WEEK Silver Logie Award for Most Outstanding Actress in 2009 โ an achievement her late mother, Kitty, who died of cancer in 2015, was incredibly proud of.
โSheโd watch anything I did โ even if it was through her hands when I was doing Underbelly,โ Kat recalls with a laugh. โIt felt like the sky was falling when she died, but Iโm a glass-half-full kind of person and count myself lucky I had such a great mum, who was at every opening night.โ
โSheโd love Black Snow; she loved a mystery drama.โ
