Francisco 'Frankie' Muniz landed his breakout role in 2000 at age 14 as the star of 'Malcolm in the Middle'. Throughout the show's run, Muniz appeared in several films, including 'Agent Cody Banks' in 2003 and its 2004 sequel. After the sitcom ended in 2006, he starred in the movie 'Walk Hard: The Dewey Cox Story' in 2007 and smaller films, moved to Arizona and became a drummer for the band Kingsfoil.
Muniz largely retired from acting after 'Malcolm in the Middle' ended and worked as a professional race car driver for a while. In September 2010, he said on his Twitter page, after a user called his acting skills 'awful': Yeah, but being retired with $40,000,000.00 at 19 has not been awful. Good luck moving out of your moms house before youre 35.'
About two weeks later, he Tweeted: 'After 4 years of retirement from Hollywood... I think I'm gonna pull a Michael Jordan...'
In 2012, Muniz guest starred on the ABC sitcoms 'Last Man Standing' and 'Don't Trust The B---- In Apt. 23' and continued to perform with his band. On November 30, he was hospitalized after suffering a mini stroke. He suffered another one almost a year later, in November 2013. He appeared to have recovered, later tweeting about cars.
