Actor RJ Mitte, who rose to fame playing Walter "Flynn" White Jr. on the hit series "Breaking Bad," has died at age 34. His on-screen dad, Bryan Cranston, said he was “in deep despair,” adding that Mitte used his own experience as an actor with cerebral palsy “to be a vocal advocate for performers with disabilities.” #RJMitte #Actor #BreakingBad #BryanCranston
