4. Ultron James Marsters
Again, as Ive pointed out numerous times throughout this list, I have no real knowledge of the processes going on inside Marvel, so a lot of these picks are to a certain extent wish-fulfilment. That being said, how cool would it be to have James Marsters being the voice of Ultron? Ill answer that for you extremely. If nothing else, it would make the Buffy fans in the room stand up and cheer. The thing is though, it might seem more possible than you think. Obviously he and Jos Whedon are well-known to each other already, and such is the nature of the Avengers that you dont need a marquee name playing the bad guy. Yes, I know we had Tom Hiddleston in the first one, but by the time 2015 rolls around, all the big names might be even bigger. Hell, by that point, Chris Hemsworth might even have an Oscar on his mantelpiece (for Rush, apparently hes great in it). So what Im saying is that the franchise will not live or die based on who voices Ultron the fact Ultrons even in it will mobilise the geek masses, and the calibre of the rest of the cast will bring in the regular folk. Whedon clearly knows this, so it might be almost too tempting to create a further level of geek nirvana by giving his Spike with all his velvety, malevolent tones a speaking part as Hank Pyms awful creation.
