It sounds like Worden, but with the mechanical sound effects, it could have been anyone doing that voice. It wouldn't surprise me if this trailer is test animation, since the show itself isn't due until 2011-2012.
I have some extra news bits from the Toonzone board that may as well be reposted here:
- According to Newsarama's Blog, Brian Reed (SECRET WARRIORS, MS. MARVEL, THE ILLUMINATI, CAPTAIN MARVEL) will be writing an episode of this show. He also wrote the story for the video game SPIDER-MAN: WEB OF SHADOWS.
- Via Chris Yost's blog, Yost states that the pilot episode has "the birth of the team", and that means the Avengers are not "pre-existing".
To be honest, I don't envy the task of trying to introduce 7 characters within one pilot episode. I'm sure it will be 2-3 parts like nearly every team cartoon pilot episode since X-MEN, but still. Of course, I imagine that the producers likely feel the audience is at least "vaguely" familiar with who Iron Man and Hulk are.
Hopefully we will see more production images and information in 2010. 52 episodes have been ordered initially, so Marvel has some faith that this will do well. Granted, it may mean that their deal with Disney means they know 100% that DISNEY XD will air the series and order a certain amount of episodes. In prior years, or at least since X-MEN EVOLUTION ended in 2003, Marvel has usually scrambled to find channels/networks to air their shows. SPECTACULAR SPIDER-MAN's channel destination was unknown for ages. And one gets the feeling Marvel never saw much faith in CARTOON NETWORK even before FANTASTIC FOUR: WGH was treated rather poorly. They also likely never liked dealing with Kid's WB. The Disney deal, at the very least, sets up a clear network for Marvel animation that Marvel hasn't had since they were FoxKids' best friend in the 90's.
Unlike with SPIDER-MAN and X-MEN cartoons, though, the wind is really at Yost's back here. There has never been an AVENGERS TV show anywhere that was any good. There is literally no shadow to escape from or some prior show to live up to; this show will be the trail-blazer. Yes, there were other team shows (nearly any team show will be compared to JLU, especially if the action isn't perfect within the first 22 minutes), but the Avengers have only had the CAPTAIN AMERICA 1966 segments, and the 1999 abomination.
There is a part of me that wishes that at the very least we had another heroine there, instead of having Wasp as the token girl. It is how the Avengers started out, but most team shows these days usually have at least 2-3 girls out of a cast of about 7-8 characters. Bruce Timm & Co. were willing to buck history to stick Hawkgirl in JUSTICE LEAGUE to have that effect. I still get this awful feeling that the Hulk is there for two reasons; recognition and to reuse design/production material from his own aborted cartoon. Of course, to be technical, the Hulk was in the first 2 issues of AVENGERS (not including Joe Casey's "year one" style mini) and popped up a few times before they thawed out Capt. America. It is shrewd strategy to want to have as many recognizable characters as they can to start off. Still, the Hulk usually doesn't do well on teams, and a season finale in which he turns on the Avengers would be the most predictable plot thread in history, and one I'd rather not see again.
The trailer at least shows that sense of Avengers history with Kang and Pym & Jan working on a prototype that is clearly Ultron. The challenge will be to be faithful to some of those old stories without making the show seem cheesy or retro. Yost & Co. will have to know where to update or modernize to be effective.
Chris Yost usually knows his stuff, so I'm fairly certain it'll be pretty good. Although, again, the lack of ANY positive Avengers TV experience that wasn't partially based on Ultimates works in the show's favor.
