Any actress who someday portrays Dolly Parton in a film about her life will need to put in more than 9-to-5 hours.

The country music icon, 77, revealed recently on "CBS Mornings" what a hypothetical biopic of her career would entail should one get made.

Broadcaster Nate Burleson asked the "Jolene" crooner about a script for a potential feature film that had been "floating around" in the past few months. Burleson also wondered which actress would embody Parton's unique charm and persona.

Parton replied: "Well, I don't know. I think when it gets to that point, we'll be auditioning a lot of different people. And we'll just have to see."

She was then asked about what traits the casted actress would need to play her accurately.

"Well, she would need to have my spirit, I would think," Parton noted. "She'd have to have a lot of that fire and spunk."

The Grammy winner went on: "And she'd have to have some boobs, of course. Whether they were homemade or whether they were real."

"She'd have to look the part. She'd have to be a little over-exaggerated … That would be pretty easy, even a boy could do that," Parton concluded.

The "9 to 5" actress previously expressed her wish to create a musical biopic of her life.

"I've been talking about doing my Broadway musical, and we were really, really way out ahead of that, and then COVID hit and that changed my mind about a whole lot of things," Parton admitted during an appearance on "Mr. Nashville Talks" Feb. 23.

However, the philanthropist is still gunning to create a production to tell her story.

"I do intend someday to be on Broadway, but I'm thinking now that I might do my life story as a feature," she said of possibly turning her life into a big-screen flick. "Maybe possibly even a musical feature, so we're in talks about that. "

In a 2021 interview with "Southern Living" magazine, Parton desired that her would-be film would have several women to portray her throughout her six-decades-long career.

"We'd probably have to have — as long as my career has been — like, a little Dolly and a middle Dolly and then the older one," she said.

And in 2020, Parton hoped that Broadway star Kristin Chenoweth would take the reins as the blond bombshell. "She's just absolutely fantastic," she told Marie Claire at the time.
