“Everyone was so afraid to stand up when certain people were controlling or rude or disrespectful, like they walked on pins and needles,” Frankie explained. “I remember being so mortified by watching people afraid to stand up for themselves, kind of like, ‘Say something!’ I didn’t care if they told me I was never going back, because it was worth it to me, you know what I mean?”

He continued, “I didn’t care if they told me I was never going back, because it was worth it to me,” before adding, “It helped that the show was based around me.”

Frankie is credited in all 151 episodes of Malcolm in the Middle, which ran for seven seasons between 2000 and 2006.
