An international TV spot for Iron Man 3 has gone online.  The spot still has the grim tone of almost everything we've seen so far, but it also has the same amount of action.  It also has a very cool ending, and fans of the comics will enjoy the reference even if the reference will probably be unnamed in the actual film.  That's all I'm going to say because some might consider what happens to be a minor spoiler.

Hit the jump to check out the TV spot, but again be warned that it contains a minor spoiler.  The film stars he film stars Robert Downey Jr., Gwyneth Paltrow, Don Cheadle, Guy Pearce, Rebecca Hall, and Ben Kingsley.  Iron Man 3 opens in 3D on May 3rd.
