Just watched the movie last night and really enjoyed it. I like the adventure, super hero movies. The WWI scenario topped it off for me.

I whispered to my lady, "I hope they show Lugers!"
Yes, a few Lugers worked their way into several scenes, as did other period weapons. In one an Imperial German officer and bad guy, unholsters his Luger and blasts a subordinate. Later the same bad guy gains super human strength from snorting a chemical and demonstrates his strength by crumbling his Luger like a two week old breakfast scone. I gasped in horror of the thought of a needlessly destroyed Luger. Ok, i know it was a movie prop, but i still felt the pain. LOL
Fun movie. Go see it.
