Rose Byrne's new Apple TV+ series, Platonic, has been a hit with audiences and critics alike.
But many American viewers have been left confused by the Aussie star's accent, which has become a mix of American and Australian over the many years that the Sydney-born actress has spent working in the United States.
In the comedy, in which the 43-year-old stars alongside Seth Rogan, Rose uses her natural accent, unlike the bulk of her roles where she has starred as an American character.
After the series premiered this week, slews of viewers stateside took to Twitter to share their confusion over how the actress speaks.
'I'm so thrown off by Rose Byrne's accent. Why does it keep changing mid-sentence?' one person asked.

'Trying to watch Platonic and it's so distracting how Rose Byrne's accent keeps flip-flopping between American and Australian,' tweeted another.
'Why pray tell does Byrne only have an American accent 60% of the time? So odd! Do you think actors know when they lapse back into their own accents?' said another.
'I want to watch Platonic but I get too distracted by Rose Byrne's accent jumping back and forth,' someone else chimed in.
'What is happening with Rose Byrne's accent in Platonic? Why is it switching every other sentence? I'm super distracted,' one more tweeted.

'I'm so confused by Rose Byrne's accent in Platonic' someone wrote, while another viewer mistook her for British.
'I do not understand what's going on with Rose Byrne's accent in the show Platonic. Did I miss something? Did her character spend her childhood in a British boarding school or something?' they wrote.
'Me watching Platonic: What is this weird ass accent Rose Byrne has me googling 'Rose Byrne is Australian?' Did we know this?' one viewer asked.
'This isn't how Nicole Kidman sounds… I think she's slipping in and out of American and Australian and it sounds crazy lol' they added.

One fan had an explanation, writing: 'The Australian accent is the hardest to emulate, but the easiest to lose. Rose Byrne's accent in Platonic is all over the place - a result of being an Aussie that's lived and worked in the US for years.
'My favourite example is when she says 'can't' both ways in one sentence.'
It's no surprise that Rose has picked up an American accent, as she first moved to New York in 1999 when she was just 20 to peruse her big screen career.
The Neighbors actress lives in Brooklyn with her partner Bobby Cannavale and their two sons, Rocco and Rafael.
In Platonic, Rose and Seth Rogan star as former best friends, Sylvia and Will, who reconnect after Will gets a divorce.
The show has been widely critically acclaimed, scoring a 92% fresh rating on review aggregator Rotten Tomatoes.
