I have written a basic narrative and character bios for the story the posters would be based on. The reason for this is because a narrative will give me the context to develop the characters and setting depicted in the posters, so they will look stylistically consistent. Without a narrative, the characters may look random and out of place.
None of these are final, and are all subject to change.
The story takes place in a futuristic city on an alien planet. A scientist is being hunted down by an unstoppable killer robot, and the space marine must protect her. However, the scientist is actually a shape-shifting mutant, and the robot is programmed to hunt down dangerous creatures inside the city, which causes it to target her.
This may be too convoluted for just a poster design. If so, I might explore alternative poster designs that show the scientist in monster form, or subtly hint that the scientist is the monster. Otherwise, I will scrap the idea and develop a simpler narrative using my characters.
The space marine:
A courageous war hero who is willing to put his life on the line to save the lives of innocent people, using only his quick thinking, his nerves of steel and his trusty ray gun. He wears a retro space suit.
The scientist:
She’s a scientist. Which field is she an expert in? All of them! She’s a stereotypical movie scientist who knows everything. She also appears to be a damsel in distress- that is, until she transforms into a terrifying monster, destroys the robot, becomes the real villain of the story and goes on a destructive rampage through the city. She wears retrofuturistic clothing.
The robot:
An unstoppable killing machine that cannot be dispatched with conventional weaponry. It only has one mission; destroy all monsters. Design based on clunky, retro, tin can robots such as Robby the Robot. However, unlike these robots, this one is bulkier and covered in armour. It has a vaguely military aesthetic, but it appears alien and its purpose is unknown. It has no facial features, only the circuitry and interior contraptions, which can be seen through a glass window reinforced by metal.
