Wow. This is going to be great.
It's great to see Ridley getting back to SF, he really is very suited to it. The only issue I can see is that he tends to sacrifice storytelling for the sake of experience, I hope that this has a strong script.
Also, I getting to utterly HATE the idea of films in the future that use current era firearms, this is as silly as having a jet pilot armed with a flintlock.
This was mentioned on The Mighty Mississippi With Trevor McDonald the other night, the Browning Machine Gun designed in 1918 is still in service even now!
So if Prometheus is set around 2083 like Scott has stated why wouldn't they be using weapons developed in the 90's or 00's ? If a gun does it's job and is reliable then they'll keep on using it, again the Uzi is 64 years old and still in service !
It is in service...just not in that form. The current M2 is not the same as the 1918 version.
Because we already have better weapons, and the uzi isn't in first line service, either. Just because these weapons still exist (lots of people I know own weapons that are more than 100 years old) doesn't means such antiques are in or would be used in any sort of service. So again, 1. Better weapons already exist, 2. energy weapons are already being used and replacing slug throwers, 3. slug throwers utterly absurd in space : in a ship, they punch holes out into space and/or holes in vital equipment/wiring, outside they are silly in that they are too short ranged and slow acting.
Finally, remember wikipedia isn't a valid source for information: facts are not determined by consensus.
Well they're still using 'slug throwers' as you call them in Aliens set in 2179.
