The
Insultingly Stupid Movie Physics site is quite fun, and not nearly as prissy as it sounds. My favourite bit's the one about the sheer
weight of all the ammunition the goodies can spray out of their guns.
Kudos to the
Firefly episode
Out of Gas for its use of space's utter silence - not just for accuracy, but for the enormous dramatic contrast that results. I also realised that there's a
Star Trek-style noisy flyby in the opening credits, but it's justified because the ship's in atmos. A deliberate joke?
