What's even more amazing is just how much ammo is used in one gun in a scene, without being reloaded. It seems that a 44 magnum contains more than 6 shots in one scene. Even more amazing is when a double-barreled shotgun which can only fire two rounds at a time, fires consistently at least five times before reloading.
In addition, and I just noticed this in SPIDER-MAN 2 was just how close the web slinger swings narrowly in between the space of an 18 wheeeler cab and the hitch without becoming entangled in the brake and trailer hitch wires.
