Screwed by the Network: A common complaint from fans over cancellation, though Joe Quesada, Arune Singh, and Josh Fine have stated it was simply a financing matter. One of the other companies reportedly folded and no substitute could be found.
Associate producer Joshua Fine had reportedly considered incorporating tie-ins with the then-upcoming cartoon The Avengers: Earth's Mightiest Heroes, such as Wolverine teaming up with Hawkeye and Black Widow on a black ops mission. (Incidentally, some tie-ins with this show did make it into The Avengers, such as Nick Fury asking one of his agents to send Whirlwind to the MRD.)
