Physics question about a spaceship destroying another spaceship?

Well, as a science consultant I would have to look at things from a rational stand point and use my scientific approach to advise the producer. The first thing I would do is determine the goal (making lots of money off of the movie). Next I would use my scientific mind to look at what past movies have done and how it has effected their sales. Movies which ignore the rules of physics and show sounds waves traveling freely through space have generally made far more money than those that choose to stick to the laws of physics. Taking into account how many other things in the movie probably defy the known laws of science, it would seem silly to obsess over the accuracy of that one at the risk of profits. Further more I would point out that most people don't really know what makes since they just want it to sound good "According to the quantifiable stratospheric law of integrity we could actual alter the atmosphere in such a way that it would confuse the enemy ships sensors long enough for us to sneak a missile through their defenses!" With that taken into account I would recommend that he use me to make things sound scientifically realistic instead of worrying if they actually are. If people said something about sound waves not traveling in space I would just have a character comment on "dark matters tendency to transmit sound waves through space" and say "How else do you think they communicated with the Apollo missions?". That would probably be sufficient enough to confuse the average viewer into believing it was realistic. As for the everything must be scientific type, they are going to be stuck wondering how that Alien knew how to use a human keyboard and every other "descrepancy". Plus, ever person who blogs about the scientific descrepancies of the movie is like free internet coverage.
