Robert Irwin has shared his cheeky top pick to portray him in a potential biopic.
The wildlife warrior has revealed Australian actor Chris Hemsworth would be his choice to play him if his life was ever turned into a film.
“Chris Hemsworth, obviously,” Irwin told UK entertainment outlet Capital Buzz.

“He’d just have to stop eating protein and stop working out for, like, six months and then he could play me in a biopic,” he joked.
“And his voice would have to be about three octaves higher.”
The 22-year-old then attempted his best Hemsworth impression, adopting a deep voice to deliver: “G’day. How you going? Let’s go for a surf. Not bad, that’s not bad.”
He later apologised for his “pretty awful” impression.
While the exchange was all in good humour, Irwin and Hemsworth share a friendly relationship and have worked together in the past.
The pair joined forces for Tourism Australia’s 2019 campaign, bonding over their shared passion for wildlife, the Australian environment and conservation.
Hemsworth has also long admired Irwin’s late father, Steve Irwin.
In his documentary, Chris Hemsworth: A Road Trip To Remember, the actor revealed his first “unofficial acting gig” as a teenager involved making a home-video parody in which he impersonated the Crocodile Hunter.
Irwin was quick to respond warmly to the throwback, saying his late father would have been “stoked” by the impression.
Chris Hemsworth’s impersonation of the late Steve Irwin
In November 2025, to mark the release of the documentary, Hemsworth shared a clip of his parents, Craig and Julie, at home watching a home video of their son’s earliest role.
In the grainy footage, a teenage-looking Hemsworth is doing his best impersonation of the late Steve Irwin.
Dressed in the Crocodile Hunter’s signature khaki outfit, Hemsworth channels his enthusiasm.
“How you going folks?” he says, slipping into his best Irwin accent.
“We’ve got a real bloody ripper in store for you today. It’s gonna be bloody unreal!”
The young Hemsworth then announces he’s tracking down a Siberian tiger Australian fox, which, as the clip reveals, is simply the family dog.
“Next week, we’ll be chasing the Australian grasshopper! Can’t wait!” he adds.
The footage was part of Hemsworth’s mission to reconnect his father with his old memories.
In A Road Trip To Remember, Hemsworth and his 71-year-old father embark on a journey across Australia, revisiting the places that shaped their lives.
The trip was prompted by Craig’s diagnosis with early-onset Alzheimer’s — a disease Hemsworth himself has a genetic predisposition toward.
Alzheimer’s is the most common form of dementia and gradually impairs memory, thinking and behaviour as brain connections deteriorate over time.
In the film, Hemsworth reveals he carries two copies of the APOE4 gene which puts him at a higher risk of developing the illness, but right now he just wants to “continue on with life”.
Throughout the road trip they explore reminiscence therapy, which involves a discussion of past experiences and events between a person living with dementia and their carers and family.
This approach often uses photos, old newspaper articles and items from the person’s past to evoke memories and stimulate storytelling.
