There is no need to copy paste random WWII images into a poster this far from release, that comes later. I myself made a simple poster since that's how the teaser poster most likely will turn out. Look at Interstellar's first poster and then mine. http://1.bp.blogspot.com/-HLpupWIwDco/UqyU0v9Rf8I/A...

I tried to make it look a little bit like an old, classic war film. It is meant to be a teaser poster.

Didn't have much time, but this is what I came up with.

I hope it's going to be Hoyte. His work on Interstellar was amazing and I think his style fits very good with the war genre.
