Richard Gadd just shocked Hollywood by gaining nearly 100 pounds for his new HBO Max series. The Baby Reindeer creator underwent a radical transformation to play Ruben, a physically imposing character. Here’s the stunning inside story.
🔥 Quick Facts
- Weight Gain: Gadd went from 151 pounds to 242 pounds between projects

From Rail-Thin to Physically Imposing Bruiser
The 36-year-old Scottish actor made an intentional choice to completely distance himself from his Emmy-winning role in Baby Reindeer. During that Netflix hit, Gadd weighed only 68.8 kilograms (151 pounds) and deliberately became rail-thin to feel vulnerable and youthful.
For Half Man, he needed to become the opposite. Gadd said, “I needed to change everything.” He transformed his voice, beard style, and overall presence. The massive physical shift helped audiences see Ruben as a completely different character from sensitive Donny Dunn.

The Ambitious One-Year Transformation Plan
Richard Gadd committed to an intensive training regimen that lasted over a year. He trained six times weekly, sometimes completing two sessions in a single day. High-protein meals arrived regularly from a specialized company in England, ensuring his nutrition supported serious muscle growth.
Unlike typical lean bulking approaches, Gadd pursued aggressive weight gain. He worked alongside trainer David Jenkins and nutritionist Dr. Andrew Usher, who customized his carb-heavy diet at the start. The approach was designed to build muscle while maintaining a realistic, natural appearance for the character.
Behind the Scenes of the Physical Journey
Half Man marks Gadd‘s bold follow-up to Baby Reindeer, where he created, wrote, and starred. His body transformation became central to embodying Ruben, a character exploring themes of toxic masculinity and male rage. The actor never wanted a “veiny, steroid look” but rather authentic physical presence.

“I knew in order for people to buy me as Ruben I needed to get away from Donny Dunn in almost every single way I could. A huge, huge difference.”

The Dramatic Brother Story That Captivated Critics
The limited series introduces Ruben Pallister, an angry, physically threatening man with a troubled past. Jamie Bell plays Niall Kennedy, his estranged brother, creating a complex dynamic between the characters. The show explores their relationship spanning decades, from the 1980s through present day.
Early reviews praise Gadd’s “entirely transformed” performance. Rotten Tomatoes gave it 75% from critics, with reviewers noting the show is violent, thrilling, and brilliantly acted. Gadd told audiences the transformation wasn’t just physical but emotional and vocal as well.
Why Did Richard Gadd Push Himself So Hard for Half Man?
After the intense, traumatic experience of bringing Baby Reindeer to life, Gadd deliberately created distance mentally and physically. The 50-pound weight gain represented a complete reinvention, allowing him to shed his previous identity. His trainer and nutritionist pushed him relentlessly, ensuring he never “slacked off.”
The actor explained that simply playing a different character wasn’t enough. He needed audiences to forget Donny Dunn entirely. The dramatic body transformation, combined with changes to his voice, facial hair, and mannerisms, achieved that goal. Half Man officially launched April 23, establishing Gadd as one of television’s most committed transformative performers.
