Re: The chaingun scene. I don't see why this is only being raised now. But anyway. If I had to guess who wrote that without knowing, I'd say Paul Anderson. That description leaves anyone over 16 redfaced just reading it. I mean come on. Bullet-time was old-hat by the first Matrix sequel.
Having said that, those 3 Predators are such a departure from the descriptions we read, I think we should take most of what we read with a grain of salt. But then, wasn't dialogue from the script overheard on the set?
A draft, I guess.
