New G.I. Joe Cartoon In The Works
The boys over at moonbase2 have posted a nice podcast featuring an interview with Michale Bell, the voice of Duke from the original G.I. Joe cartoon series. In the interview, we learn that Bell is auditioning for the role of General Hawk in a new 26 episode G.I. Joe cartoon. No other information is known as of right now in regards to a release date, other cast or character info, or a story line. It can only be speculated that it will probably tie in with Rise of Cobra in some way, or possibly coincide with the release of the Pursuit of Cobra line. Until we here official word, anything is possible.
