Amazed where this has gone. My intial statement was, in part, supposed to be ironic humor. It amazes my the detail they will go to in making bomb blasts just so, uniforms reasonably correct, scenary detail perfect, recreation of battles to the letter and many other details yet miss some other things that are so plainly visible to those that were in the military.
On the other side of the coin there were Hollywood pranks perpetrated on the public as well. In the movie "Wake Island" is one I wonder how many people caught. Willian Bendix is a mud Marine and Robert Preston is his buddy. Bendix is Pvt Aloysius K Randall and he has a little dog named Skipper (supposedly the only dog on the island). After an attach Skipper is nowhere to be found. Finally one of his buddies comes and tells him to close his eyes and leads him to a pile of debris where, wonder of wonders, there is Skipper with puppies!!!! Pvt Randall pulls her out and a couple of puppies and holding the dog under its front legs turns toward the camera and says something like "Skipper, how did this happen?" Indeed, Skipper is Skip, undoubtedly a fully mature male dog and Bendix even semi-smirks at the camera. In this movie they also painted Aeronca L's as Zeros, weird.
