From the beginning of his career, actor James Arnold Taylor specialized almost exclusively in voice-over work and evinced a predilection for sci-fi- and fantasy-themed material. He took assignments as original characters, and also perfected the art of "voice-doubling" for A-listers whose scheduling conflicts prevented them from re-looping, such as Steve Carell, Billy Bob Thornton, and Nicolas Cage. Original characterizations included such voices as Raul, Rick, and Kid Walla in The Animatrix, Wooldoor Sockbat in all three seasons of Drawn Together, and Leonardo in the big-screen animated adaptation of the Teenage Mutant Ninja Turtles, TMNT (2007). In 2008, Taylor voiced Obi-Wan Kenobi in the animated feature Star Wars: The Clone Wars. Taylor's television resumé includes guest spots on series including The PowerPuff Girls, Kim Possible, and What's New, Scooby-Doo?
