Lucy Liu, Jackie Chan Team for Toon

Spicing up its toon hit Jackie Chan Adventures, both Lucy Liu (Charlie’s Angels) and Michael Rosenbaum (Smallville) will be making guest voice appearances on the series’ Jan. 31 broadcast.

In the episode titled “J2,” Jackie’s feisty niece, Jade, gets the surprise of her life when she comes face-to-face with the adult version of herself–voiced by Liu. The adult Jade arrives from the future, bringing knowledge of the only way to save the world from the Age of the Dragons. Once she gets over the shock of meeting her future self, Jade learns to use her grown up image in her ongoing quest for knowledge.

As the infamous Lex Luthor on the WB’s Smallville, Rosenbaum lends his voice to Drago, the son of Shendu, who travels back in time to retrieve the magical dragon’s teeth needed to resurrect his father and ensure the future Age of the Dragons (which Jade has returned to destroy).

Jackie Chan Adventures is produced by Sony Pictures Television for Kids WB! Jeff Kline, Duane Capizzi, Jackie Chan, Willie Chan, Brian Gersh and Solon So serve as exec. producers. The episode airs on Kids’ WB!’s Saturday morning line-up on Jan. 31, 2004 at 8:00 a.m. ET / 7:00 a.m. PT.
