Roy Frank "RJ" Mitte III (born August 21, 1992) is an American actor and producer. He is best known for his role as Walter "Flynn" White Jr. on the AMC series Breaking Bad (2008–13). Like his character on the show, he has mild cerebral palsy. After moving to Hollywood in 2006, he began training with personal talent manager Addison Witt. They sought out acting opportunities where his disability would serve to educate viewers, which led him to audition for the role in Breaking Bad.
Mitte was born in Lafayette, Louisiana. He was delivered by emergency caesarian and was not breathing at the time of his birth, which resulted in permanent brain damage. He was adopted a few weeks later by Roy Frank Mitte Jr. and Dyna Mitte, who later separated. He was diagnosed with cerebral palsy at the age of three, and doctors put his legs in casts for six months in an attempt to straighten his feet.
Mitte was fitted with leg braces and used crutches throughout most of his childhood; however, over time, his body became stronger through sports and exercise and he no longer needed any walking devices by the time he was a teenager. In 2006, he moved with his family to Los Angeles, where his younger sister Lacianne Carriere had received an offer for a role in a film project.
After receiving several roles as an extra, including in the Disney series Hannah Montana, Mitte became interested in films and decided to take acting lessons. Shortly after, he was offered the role of Walter White Jr., who also has cerebral palsy, in the AMC series Breaking Bad. At the 2013 Media Access Awards, Mitte received the SAG-AFTRA Harold Russell Award for his portrayal of Walter White, Jr. on the series, and also presented the eponymous RJ Mitte Diversity Award to deaf actor Ryan Lane. The Screen Actors Guild named Mitte as the spokesman for actors with disabilities and he is the representative of "Inclusion in the Arts and Media of Performers with Disabilities", which employs artists with disabilities.
Mitte will star in the film Wildflowers. His sister, 9-year-old Lacianne Carriere, will also be in the film. Mitte is one of the producers on the project. He is also working as a producer on a documentary called The Kids of Widney High. He hopes to branch out into directing. In 2011 he starred in the short horror film Stump. That same year, he worked as executive producer of the documentary Vanished: The Tara Calico Story, that deals with the disappearance of Tara Calico. In 2012 Mitte was cast in the thriller film House of Last Things.
