Josh Brolin To Voice Thanos In Avengers 2

Thanos will appear in Avengers 2 long enough to propel him as the main villain in Avengers 3. (DC and Warner Bros., you're being reminded yet again that you have a lot to catch up on.)

And to voice Thanos, since Thanos will pretty much be a CGI character given his physical size, Marvel is said to have recruited another very talented Josh Brolin (although his previous few films haven't been that well received).

However, given the talent and level of fame of Brolin, I am going to speculate that there will be some motion-capture / performance-capture involved. If this is going to be true, then it will definitely be very interesting to see what Brolin can do with a character like Thanos. If it's just voice-acting, then I'm not that interested.
