Soundtrack is Concerto No. 4 in F Minor, Op. 8, No. 4, RV 297 - 'L'inverno': I. Allegro non molto by Vivaldi, if anyone's curious.

Wow - there's a firearms handling fail. Check out the pistol from 0:21 to 0:31. See that shiny brass thing sticking out of the top? Looks like someone had a failure to extract and had no idea how to clear it.
Now, zoom...and enhance.

Freudian slip anyone?
