With Thor 2 beginning production this month in London, it sounds like Marvel has plans for what to film there right when the Odinson finishes. According to Latino Review, Marvel wants to put Edgar Wright’s Ant Man into production when Asgard clears out in order to get it out in 2014. The site says it’s still up in the air on how it’ll affect World’s End, but it sounds like Marvel is dedicated to getting it into production as fast as possible.
That would mean that 2014 would have Captain America in the summer, Guardians of the Galaxy in August, with Ant Man likely arriving either for Thanksgiving or Christmas. Then, The Avengers 2 would likely arrive in Summer 2015 with a huge cast of new characters to fight off Thanos.
