"I was involved in a web cartoon of Kung Fu with WB a few years back"

This quote by David Carradine is referring to his participation in the Warner Bros. animated series, "Kung Fu: The Legend Continues". The show ran from 1993 to 1997 and starred Carradine as the primary character, Kwai Chang Caine. The program was a continuation of the original "Kung Fu" series that aired in the 1970s. Carradine's participation in the web cartoon was most likely as a voice star, offering the voice of Caine for the animated series. The show was a success, running for four seasons and amassing a devoted fan base. Carradine's involvement in the web animation was likely a great experience for him, as he was able to repeat his function as Caine and bring the character to a brand-new generation of viewers.
