There are many more pics of the G.I. Joe actors in their costumes over at What Would Tyler Durden Do, including additional pics of Rachel Nichols as Scarlett, Ray Park as Snake-Eyes, and also Dennis Quaid as Hawk... who looks like a cross between Solid Snake and General Bernard Montgomery.
I haven't seen that many tight butts and rubber nipples in a movie since Batman and Robin: is Joel Schumacher an executive producer on this thing?
Seriously though, I look at these characters, and I feel no attachment to them. No empathy with them at all. The G.I. Joe characters from the Eighties franchise were well-grounded personalities: most of them (other than Snake-Eyes) we were given their names, where they were from, a bit of their history. Their individual costumes were not just a reflection of those characters, they helped to define them too. I see these "G.I. Joe" movie characters, and all I can think of is "They've become nothing more than toy soldiers."
And where is that big crimson Cobra sigil on the Baroness's outfit?
