back-to-back poster — Oversized title, two figures, stacked type

A dark sci-fi horror movie poster shows two colossal extraterrestrial creature heads looming over an adult man and an adult woman aiming pistols back-to-back in a night street, with a stacked white-and-red title treatment at the bottom. The background is a near-black void, its edges dissolving into deep blue shadow. In the upper-left corner, a biomechanical extraterrestrial head lunges into view, its elongated skull gleaming like polished metal with an open jaw of needle teeth. An inner jaw protrudes from its mouth, and its ribbed neck coils back into the darkness. In the upper-center and right, a second colossal head dominates: a heavily armored hunter with a scarred metallic face, ridged brow, and dreadlock-like tendrils. A small glowing red targeting dot burns at its temple, the only warm light in the upper half. Along the right edge, two long curved blades sweep downward, their edges catching a cold blue sheen. The two heads face each other across a shaft of pale blue light that splits the upper frame. In the lower-center of the frame, an adult man and an adult woman stand back-to-back on a deserted night street, each aiming a pistol outward. The adult man on the left wears a dark shirt and holds his weapon in a two-handed grip toward the left. The adult woman on the right wears a dark red top and jeans, her pistol leveled toward the right with both arms extended. Behind them, the street recedes into a hazy blue distance with parked cars, street lamps, and faint building silhouettes. A few small distant figures walk in the far background, nearly lost in the haze. In the bottom-left corner, a shadowy figure lurks at the frame's edge, half-swallowed by darkness. Across the bottom third, the "TITLE" treatment stacks in three tiers: large widely spaced white capitals on top, a small "VS" beneath them, and a final word in widely spaced crimson capitals at the base. The white letters are clean and monumental, while the red word glows faintly against the black. The lighting is a cold blue night wash from above, rimming the creature heads in metallic highlights while the street below glows with distant lamps and a central shaft of pale light. Deep shadows drown the corners and the lower background, and the red targeting dot and the red title word provide the only warm accents. The palette is built on midnight blue, steel cyan, and black, with the pale white title and the crimson accents cutting through the cold. The composition balances the twin looming heads crowding the upper half against the small armed adult pair and stacked title in the lower half, pairing the cold midnight-blue palette of the polished sci-fi horror style with a mood of overwhelming, apocalyptic dread.
