Megan Gale ditched her hairbrush, make-up and even her clothes while filming Mad Max: Fury Road.
She isn't nude for the whole movie but did have to strip off earlier than expected into the filming process.
"I'm pretty nude, that was my first day on the job, that was dayone. That was actually meant to be day three but the shooting schedule changed," Gale told AAP.
Gale, who plays The Valkyrie, says director George Miller, who also created the first three Mad Max movies, had a good reason for her scene in the altogether.
"George assured me that he would handle it all very well and very tastefully, and there's nothing sexual about it. There's a reason my character's nude so it's relevant, it's not nude for the sake of getting nude," she said.
Gale walked the red carpet in Sydney on Wednesday night for the film's Aussie premiere.
The film's stars Charlize Theron and Tom Hardy didn't make it Down Under but are due to be at a screening in Cannes on Thursday.
It meant Gale was one of the biggest drawcards locally, which isn't bad for the model's feature film debut.
However, it hasn't all been plain sailing. Aside from being in her birthday suit on her first day, she also had to act alongside Oscar-winner Theron.
"That was pretty intimidating," she said."I was more worried about the scene with her than being nude because I didn't want to let her down.
"So that was pretty terrifying. Her character in the gritty, post-apocalyptic drama is a far cry from her usual glamorous self."
"The Valkyrie is a little bit more dishevelled than this," Gale said of her red carpet look - a chic black trouser suit.

"The Valkyrie's quite rustic ... she's part of this travelling tribe through the wastelands. There's no glamour, there's no hair and make-up happening," she said.
"They're just trying to survive, their resources are fairly low."
She describes the women as resilient and praises Miller for the strong female roles he created for the film.
But this one was a long time coming for the actress who had been cast in 2007 as Wonder Woman in Miller's, now abandoned, Justice League film.
But Gale has finally made her debut, thanks to the director.
"I think George Miller's always been very pro having women in his films that are very strong and independent and capable, and I think it's so lovely when someone wants to portray women in that way as opposed to the damsel in distress," she said.
