After footage from The Avengers 2 seemingly revealed a grey-colored Hulk, many online speculated we would either be seeing the Ultimate Comics version of the
Green Grey Goliath, or a personal favorite of mine, maybe Joe Fixit.
To add to that, promo art and merchandise also featured the Grey Hulk.
So what happened?
It turns out the Hulk was initially to become Grey when Scarlet Witch hexed banner during the Hulkbuster scene.
Check out an Avengers 2 Design FX reel above with plans for the Grey Hulk mentioned.
Here is the blurb:
Initially Hulk was planned to turn grey when he's angry Hulk in the Hulkbuster sequence, but - hey, everybody wanted the green guy - so in the end, ILM just changed his eyes to make him look more sullen, but he is under the control of the Scarlet Witch.
That's too bad they didn't stick with the original idea. Now that would have been really awesome and added something more as Hulk/Banner is the only hex dream we didn't get to see.
First Loki, now Grey Hulk! What's next, Marvel?!
