Breaking Bad star RJ Mitte will form part of the largest ever team of disabled presenters for Channel 4´s coverage of the 2016 Paralympic Games.
Almost two thirds of the on-screen talent working on the Paralympics coverage will be disabled, including all four of the daytime presenters.
The Rio 2016 Paralympics broadcasters will be led by Clare Balding and The Last Leg's Adam Hills alongside Formula 1 presenter Lee McKenzie and former Olympic champion Jonathan Edwards.
Clare said: "It is a privilege to return to Channel 4 for the Paralympics and build on our Bafta award-winning legacy of the 2012 Games."
She added that the coverage four years ago "helped shift Para sport from the margins to the mainstream".
US actor RJ, who has cerebral palsy, is an advocate for disability charities and will be based in Rio, providing comment on each day's action.
The 23-year-old rose to fame after starring as Walter White Jr, son of the character played by Bryan Cranston, in hit US series Breaking Bad.
RJ said: "I have nothing but admiration for these superhuman athletes who refuse to be confined by what nature has dictated. I cannot wait to witness them push themselves to the limit and be a part of Channel 4´s ground-breaking coverage."
Channel 4´s daytime presenting line-up comprises former Marine commando JJ Chalmers and disability campaigner and broadcaster Sophie Morgan.
They will be joined by former Paralympic wheelchair basketball medallist Ade Adepitan and former Royal Marine Arthur Williams - two London 2012 presenters returning for Rio 2016.
Irreverent series The Last Leg will be placed at the heart of Channel 4´s prime-time schedule throughout the entirety of the Rio Paralympic Games, bringing together sporting action and entertainment.
The Last Leg's Australian presenter Adam said: "From the day the London 2012 Paralympics ended, I've been in training for Rio."
This will be the biggest overseas broadcast in Channel 4 and Paralympic history with more than 700 hours of live Games coverage across Channel 4 platforms - including The Last Leg live from Rio every evening.
