Chris Hemsworth, Russell Crowe tipped to play Steve Irwin in biopic - but they're not Terri Irwin's first choice

Hollywood heavyweights Chris Hemsworth and Russell Crowe are both reportedly in the running to play the Steve Irwin in a movie about his life, but the late Crocodile Hunter's wife reportedly isn't convinced. 

According to Woman's Day, a biopic about the Australian wildlife conservationist and television presenter is in the works, and his wife Terri Irwin and children Bindi and Robert Irwin will be involved "every step of the way". 

The magazine claimed both Hemsworth and Crowe's names were in the mix for the iconic lead role, however, Terri has allegedly expressed interest in seeing Home and Away star Lincoln Lewis play her husband. 

An insider reportedly told Woman's Day it wasn't the first time the family had been approached about a project like this, but they felt the timing was now right, particularly following the birth of Steve's first grandchild, Bindi's daughter Grace. 

The source also insisted the family would want Australian actors for the film, which will follow Steve's life and love of animals, which became apparent early on. 

"Hollywood bosses love Steve's life story. He was saving lizards when he was six!" the insider reportedly told the magazine. 

"And while his story may have ended too soon, there's a real sense of closure now with how Bindi and Bob have taken up his legacy."
