Narrowed Re: Movies

a) grunts in space

Several psuedoubermensch might work for you, but I take no
responsibility
for dramatic quality.
Prototype X29A and Digital Man are two that I can remember names,
several
others only vague recollections. Terminator-style relentlessness, often
with 'bad' government, is the main theme.

b) ship -to -ship
c) wet navy battles that could transpose to space

*I* want to hear more of these.
