Inside Ethan Slater's Big Transformation for 'Wicked: For Good'

It has always been Ethan Slater's desire to portray Boq in the 'Wicked' series, but nothing prepared him for what came with 'Wicked: For Good.' As the story evolves, Boq undergoes a haunting physical and emotional transformation into the Tin Man, a change that demanded long hours in the makeup chair, intense performances, and a chance for Slater to prove his abilities as an actor. Ethan recently spoke about the part, explaining how it has put him to the test and ultimately reaffirmed his love for the Oz universe.

The Journey from Boq to Tin Man: A Role Transformed

In 'Wicked: For Good,' the second film adaptation of the popular Broadway musical, Ethan Slater plays Boq once more. Boq was seen in the first film as an enthusiastic, enamoured Munchkin who secretly harboured feelings for Glinda. However, his character journey takes a turn for the worst by the sequel. Boq gradually becomes more lonely, isolated, and resentful. When magic fails, these feelings materialize as the Tin Man, who is hollowed out and hardened, devoid of empathy and filled with fury.

Slater described that transformation as deeply primal. "There's a lot of talk about the lizard brain. That's what happens with Boq," he said, noting the character's humanity, optimism, and capacity for love are "stripped away," leaving only bitterness and anger. It was no easy task to bring that suffering to life. The actor claims that Tin Man's prosthetics and makeup required him "five hours a day" at first, but as the makeup team improved their skills, it eventually dropped to less than three. 

Slater underlined that viewers could see his true facial expressions, even though he was under the heavy metal costume: "If I lifted an eyebrow, the eyebrow lifted. If I twitched my cheek, my cheek twitched." With the exception of the Tin Man body's mechanical joint effects, all of the movement you see on film is his own, and not computer-generated imagery (CGI).

Slater saw the metamorphosis as a cathartic manifestation of Boq's emotional journey. The heartbreak, betrayal, and transformation into Tin Man became not just a part of the story but a moment of artistic growth. And amid that challenging process, there was a moment he calls his "dream day."

A "Dream Day" of Filming and the Magic of 'Wicked'

Despite the hours of makeup and the emotionally draining arc, Slater looked back fondly on what he called his "dream day" of filming: a day when everything came together—performance, prosthetics, music, and atmosphere—and he truly felt the weight of Boq's tragic metamorphosis. He characterized that day as transforming and therapeutic, when the character's sorrow, anger, and despair came to life on screen.

It was also the point at which he recognized how profoundly 'Wicked' changed him as a person and an actor. Slater claims that being a part of the 'Wicked' franchise has changed his life, something he never could have predicted when he first saw the Broadway production while on a school trip. His journey through Boq's arc has now altered his understanding of performance, empathy, and storytelling, and he is now living that childhood dream.

For Slater, the Tin Man's metallic, icy, and inflexible exterior—a symbol of suffering and betrayal—became a deeply intimate study of grief, rage, and heartbreak that took on physical embodiment. Boq's story serves as a warning about what happens when sadness taints hope in 'Wicked: For Good.' With that "dream day" behind him, and a performance that required both vulnerability and strength, Ethan Slater has proven himself capable of navigating the darkest corners of Oz—and the human heart. 

What This Means for 'Wicked: For Good' and Slater's Future?

With 'Wicked: For Good' now in theaters, audiences are getting to experience the full weight of Boq’s transformation—a haunting journey from innocence to tragedy. The film's examination of identity, suffering, and redemption is enhanced by Slater's performance and the commitment to the Tin Man's emotional and visual design. The makeup artists gave Tin Man a tragic vulnerability that makes his arc heartbreaking and authentic by fusing subtle acting with brutal practical effects.

Looking ahead, Slater isn't slowing down. In 2026, he is set to star in a new off-Broadway production, 'Marcel on the Train,' which he co-wrote. In sharp contrast to Tin Man's metal shell, the play centers on a teenage Marcel Marceau enlisting in the French Resistance during World War II, proving his commitment to conveying difficult, emotionally charged stories. 

Slater's Tin Man offers Oz lovers a new, darker viewpoint rooted in tragedy, heartache, and the frailty of hope. And for Slater himself, the role stands as a proof that sometimes, the most extraordinary transformations come from the hardest work.
