The 28-year-old has told Broadway.com of how she lost the role to Anne with a disastrous first audition (yes, there are some people in the world that do say "no" to ScarJo!).
"I sang my little heart out," Scarlett said. "I auditioned with laryngitis. I did everything I could to, like, not have laryngitis.
"And I think looking at the film now, there's no possible way I ever could have topped [Anne's] performance. It was perfect and I think fateful and meant to be."
Scarlett had Les Mis history, having auditioned for the part of Fantine's daughter when she was a child.
"The audition itself brought back so many memories of auditioning for Les Mis for the young Cosette, and it was fun for me to revisit that," she added.
So could Scarlett have pulled off Anne's vocal and emotional histrionics? Have a listen to Scarlett's singing here and judge for yourself (it's a bit too whispery-throaty for us laryngitis, maybe?):

But nothing can top American Pie star Chris Klein's unbearably off-key, over-expressive audition for Mamma Mia!:
