Here are lots of Thor things mashed up in the now rather conventional movie poster fashion.
The film has been undergoing some additional shooting recently, and as far as I know, it continues. There are stories of discord in the ranks, but I believe they’re getting overstated somewhat. The producers at Marvel Studios tend to be very hands on with the films they’re making, but it’s a policy that seems to have been very successful so far.
Thor will return on October 30th in the UK and on October 8th in the US.
