The people who made Hangar No. 5 have achieved an extraordinary feat. They successfully made a chunk of live-plus-CGI action cinema, on a shoestring budget. Their success continues even to the point of getting wrong the stuff that action movies so often get wrong - Gatling guns that go rat-a-tat-tat instead of BZZZZZ, and gold bars that appear to actually be made of cardboard. ("It's gold! It's gold!" "No it's not! It's obviously not!"*)
But I'm just carping. Sling 'em a couple of bucks if you like it. (You can download the HD version even if you don't donate.)
* The gold bars you usually seem to see in movies (in Kelly's Heroes, for instance, which is one of my favourites) seem to be roughly six inches by two inches by one inch in size. That's 12 cubic inches, which is about 197 cubic centimetres, and gold weighs 19.3 grams per cubic centimetre.
So a single bar that size would weigh 3.8 kilograms. People in a decent state of fitness who're very motivated by the desire to become wildly wealthy might be able to carry as many as eight of them at a time.
Given the spectacular piles of gold action movies like to present to the heroes, even the muscles of Clint Eastwood and the avarice of Don Rickles won't be sufficient to shift 'em all before the credits finish rolling.
(Donald Sutherland could probably scare up a trailer for his tank, though.)
I am not, of course, the only nitpicker to have noticed this. TV Tropes calls it "Hollywood Density".
