There certainly hasn't been a shortage of Thor: The Dark World posters this week, with one-sheets featuring Malekith the Accursed and Thor and Jane Foster. Today we have an alternate version of yesterday's international poster, which still features Chris Hemsworth and Natalie Portman as Thor and Jane, but swaps out the Asgard background for London. Plus, we have a banner featuring the mighty Asgardian leaping into action with his trusted hammer, Mjolnir.
