RJ Mitte, whose portrayal of Walter White Jr. on the television drama Breaking Bad brought him wide recognition, was 34 years old at the time of his passing. A spokesperson confirmed the development to AFP on Monday.
No details about the cause of death had been made available to the public by the time the news broke.
Mitte's representative, Sean Reilly, confirmed the actor's death in a statement, adding that Mitte had drawn on his public platform throughout his career to advance awareness and inclusion for people with disabilities.
His role on Breaking Bad — the series he joined in 2008 — cast him as the teenage son of Walter White, a chemistry teacher whose path leads him into running a drug empire. Widely praised by critics, the drama unfolded across five seasons from 2008 through 2013, drawing consistent recognition as a standout work in the television landscape of that era.
Cerebral palsy was part of Mitte's own life, a condition that also defined the television role he portrayed. Drawing on firsthand knowledge of disability, he brought a lived dimension to the portrayal that opened up wider discussion around how disabled people are depicted on screen.
His advocacy on behalf of people living with disabilities, and his push for fuller representation within the entertainment industry, extended Mitte's public profile well past his on-screen career. Philanthropic commitments extended to United Cerebral Palsy and Shriners Children's, where he took on an ambassadorial role, while leadership of The Mitte Foundation placed him at the helm of its grantmaking and community-oriented programmes.
Tributes from Mitte's fellow cast members on Breaking Bad circulated after word of his passing spread. In a tribute posted to Instagram, Bryan Cranston — who played Mitte's father on screen as Walter White — noted that Mitte had little acting experience to draw on when the pilot filmed in February 2007, and that colleagues around him saw his craft take shape and deepen across the run of the series into something they recognised as the work of a fully formed performer.
Aaron Paul, who portrayed Jesse Pinkman on the series, shared a message of personal loss, telling his late co-star that he held deep affection for him. The words "you will be missed" were attributed to Paul in a broadcast report.
Dean Norris, who portrayed Mitte's on-screen uncle Hank Schrader, described feeling devastated by the news and recalled keeping a watchful eye over the younger actor during production.
Marlee Matlin, whose shared screen time with Mitte in the documentary Cinemability: The Art of Inclusion sits alongside years of work pushing for disability representation, conveyed grief over his death through a statement indicating that the place he had occupied was one nobody else could take. In a brief online post, she typed a three-letter farewell abbreviation.
Mitte had conveyed to those around him that each person holds a place where they are valued and not without support. His contributions to disability inclusion and his work dismantling long-held stereotypes formed a thread running through his career that extended well past the television role he is most widely remembered for.
