Mitte was cast as Walt White Jr., a series regular, and character with cerebral palsy on AMC Network's Breaking Bad. And though Mitte has a mild case of the disorder, he had to do what all actors do: research the character and even relearn many of the challenges he had endured as a child in order to convey a more pronounced version of CP. The Daily Advertiser, a Lafayette, La., newspaper learned of Mitte's work in Hollywood and featured him in an article, noting that R.J. was homegrown, and off to a great start in Hollywood.
