How to write a sci-fi action script as outlined by Cecelia over at FilmIndustryBloggers.
Deep in the [name an uninhabited jungle or galaxy] in an abandoned [name an additionally isolated location such as an oil rig or a logging station], a crack team of [name a division of the U.S. army] special ops is sent to rescue a missing detachment of [name a group of innocent civilians (ie nuns, orphans, the blind, blind orphan nuns, etc)], only to come up against a force that is [sub/super] human. After brutally murdering [Brick Wall/Slate/2×4], the tough [black/latino] member of the team, and maiming [Hard Drive/Motherboard/microChip], the group’s geeky operations strategist, the entity shows itself to be a terrifying [alien/science experiment] shaped like a huge, grotesque version of a [name a species of reptile, crustacean or mollusk] with a [name a sharp and/or slimy noun]-like mouth. The team’s fearless leader, [Wolf/Bear/Panther], quickly realizes that if he doesn’t stop the creature, no one will, and that perhaps this battle, in addition to saving the human race, will help him [atone for/work through some of lingering emotional issues from] his recent [divorce/wife’s death/brother’s drug overdose].
