Zack Sharf Digital News Director Frankie Muniz shared on the latest episode of “I’m A Celebrity Australia” (via News.com.au) that he once “walked off” the set of his beloved Fox sitcom “Malcolm in the Middle” when everyone else was refusing to stand up to certain people who were “controlling or rude or disrespectful.” Muniz starred on the comedy as the eponymous child genius for seven seasons, but he missed two episodes because of his decision. “There were two episodes I’m not in. I walked off the set,” Muniz said, explaining that his actions were due to set tensions.
