We got our first real glimpse of Avengers: Age of Ultron last October after a clip leaked online, and now the second trailer has arrived. Suffice to say that things aren't looking too good for the Avengers in Joss Whedon's upcoming film. "Everyone creates the thing they dread," intones James Spader's Ultron, as the camera lingers on Robert Downey Jr.'s Tony Stark — further cementing rumors that Ultron is the result of a Stark project gone awry. Making a brief appearance as well is Andy Serkis (Gollum, The Lord of the Rings trilogy), along with a scantily clad figure we can't yet identify. But the real action comes at the end with an extended look at Iron Man, in full Hulkbuster armor, taking on the Hulk in a massive fight: a fight he probably knew would have to happen sooner or later.
Things are going to get very, very messy.
