In 2010, Zito filed a $5 million lawsuit against the cable network FX, alleging that he had a development meeting with them in 2006, in which he pitched the idea of an outlaw motorcycle group. He alleges that FX blew him off and then stole his idea, which became the FX show Sons of Anarchy. On December 11, 2011, a court judgment was ruled against Zito. Zito appeared in Sons of Anarchy season 5, as Frankie Diamonds. He also appeared in SOA creator Kurt Sutter's Discovery Channel documentary series, Outlaw Empires.
