It looks like Robert Downey Jr. and Jon Favreau will be working together again, in a non-Iron Man capacity; as Favreau has reportedly signed on to helm the Downey Jr. vehicle, Cowboys And Aliens. The fun sounding production is apparently based around what happens when a bunch of cowboys and Indians stop fighting, on account of a giant alien spaceship that lands in the middle of a them during a scuffle. It sounds like a right proper blast, and with Favreau at the helm, this really could be a cracking film. The two have completed principal photography on Iron Man 2, which will be out at the end of April.
