US retailer Target has unveiled exclusive packaging for the Iron Man Blu-ray which went on sale across the pond today. The  two-disc  BD edition is housed in its very own ’shell head’ with the red and gold plastic fascia of Tony Stark’s Mk III armour staring out of the box. If exclusive packaging helps Blu-ray’s popularity, we’re all for it, although we doubt we’ll see Iron Man’s plastic Blu-ray head over here.
