Several sites, including The Flick Cast website, confirm that the voice actors for Spider-Man in the Ultimate and Amazing dimensions have been cast. Here's an excerpt from The Flick Cast site:
"It looks like Spider-Man will be getting some veteran voice acting behind it. Josh Keaton who voiced the Spectacular Spider-Man animated series in 2008 will be lending his voice to the Ultimate Spider-Man. Dan Gilvenez from the 1980s Spider-Man and His Amazing Friends series will be taking on the role of Migeul O'Hara as Spider-Man 2099.
From the 1990's Spider-Man: The Animated Series, Christopher Daniel [Barnes] will be Spider-Man Noir. Finally, the most impressive of the list comes from Neil Patrick Harris from the short-lived MTV CGI Spider-Man series who will take the helm of the Amazing version of Peter Parker."
There's much more there, including news on eight of the confirmed villains in the game. What do you guys think of Harris and Keaton being the other voice actors for Spider-Man?
