In 2024, Monica Barbaro amazed audiences and critics alike with her incredible 40-pound transformation for the biographical film A Complete Unknown, in which she plays the iconic folk singer Joan Baez. Transitioning from 170 pounds to a lean, elegant 130 pounds, Barbaro’s physical evolution transcended a mere costume—it involved channeling a cultural icon with integrity and discipline.

But Monica’s was more than a number on the scale; it was a demonstration of mental clarity, physical strength, and the power of intention—a unique blend of strength and elegance.

The Role That Started It All: Why Monica Needed to Transform

When Monica won the role of Joan Baez—alongside Timothée Chalamet, who played Bob Dylan—she knew she had a task ahead of her that involved more than simply talent.

“To become Joan, I needed to feel like Joan—physically, mentally, spiritually. That meant becoming physically who she was in the 1960s,” Monica said in an IndieWire interview.

Joan Baez was the epitome of grace and poise, with a slender build and vibrant energy on stage. For Monica to embody such poise, she needed to undergo a considerable physical transformation—not for vanity reasons, but to authentically perform.

Her mental tangibility and emotional readiness ultimately became just as important as her waistband.
