>In Hollywood it's more exciting if spacecraft actually do something rather than just sit there.

Dangling cables, bags, sleeping bags etc are more action than actors always having to walk to the bridge just to talk to someone.

>That means accelerating to go somewhere else, preferably at as many Gs as dramatically possible. That requires a shipshape interior :)

...with no safety belts.

>I thought the ISS was never subjected to any accelerations at all but that's not quite true. Apparently there are periodic burns by either the station's built in correction thrusters in the Zvezda module, or by attached spacecraft. According to http://weebau.com/iss/zvezda.htm there are two thrusters with a "thrust" of 315kg ( x 9.81 = 3090N ). Doesn't say if that's total thrust, or thrust per motor. So, could be as much as 6180N.

That would be 315kp actually, if anyone still uses kiloponds for anything. But the distinction between gram, as a unit of measure of mass, and pond as one of force, was drilled into me early on and I, obviously, didn't forget it).

>One gee is about 9.81 m / s^2 so the ISS's acceleration during orbital boosts is about 0.0014g, or 1.4 milligees.

You probably get more acceleration in your wrist while tipping a hat.
