I still have not seen Gravity so to anyone who is worried about this being a spoiler you can calm the hell down. The scene used in this re-cut is a scene that is shown in the preview. So unless you think watching the trailer to Gravity is a spoiler, I think you are fine.
Good, we got all that cleared up? Now please enjoy editor Krishna Shenoi’s re-cut version of Gravity featuring Superman! *Spoiler: Superman saves the day because he is Superman. Enjoy!
