If you've seen Iron Man 3, you know what Extremis is. While the movie had a devisive plot element, I really liked how the extremis soldiers were utilized. And the concept arts for this movie is awesome (who can say no to a shirtless hunk glowing red and growing back his arm?)
It was nice to see Guy Pearce shirtless (I've been admiring his beautiful body since Memento),
Though I found James Badge Dale's character Savin to be even more irresistible. Even though he barely had any lines, and never took off his shirt, he was still hot as heck to watch onscreen.
