Successor of Mako Iwamatsu
Contrary to internet rumors of being Mako Iwamatsu’s understudy in preparation for voicing Iroh in Avatar: The Last Airbender, Baldwin had actually earned the part by auditioning for it. He first began voicing the character for brief pieces of dialogue in the show’s second season due to Iwamatsu being unable to record for them before passing on, all of which were mixed in with the material Iwamatsu already completed. Baldwin would later voice the character full-time for the final season, various video games based on the franchise, and for the second and third seasons of The Legend of Korra.
Before The Last Airbender final season aired, Baldwin also performed a substantial portion of Splinter's dialogue in the movie TMNT after Mako died during production. His recordings would once again be mixed in with Iwamatsu’s, thanks to their uncanny similarities.
