back-to-back poster — Stacked Lines, Serif, Diagonal

A photographic martial-arts movie poster centers two masked adult figures standing back to back, each gripping a straight sword, against a huge red-and-gold circular emblem on a black background. Across the entire background, pure matte black stretches from edge to edge, swallowing every detail outside the central medallion. At the center of the composition, a large crimson-red disc ringed with brushed gold fills the middle two-thirds of the frame like a rising sun. On the left side of the frame stands an adult man with a shaved head and a small topknot, his fierce eyes fixed on the viewer above a black cloth mask. He wears a black satin martial-arts robe whose folds catch sharp white highlights, and his left hand rises in an open claw beside his head. In his right hand he grips a long straight sword pointed downward, a bright starlike glint flashing on the steel blade. On the right side of the frame stands an adult woman with black hair pulled tightly back, her sharp eyes meeting the viewer above her black mask. She wears a black satin robe with a high collar, and her right hand grips a straight sword with a round gold disc guard, held diagonally across her body. Her left hand extends in an open-palm block, fingers pressed together. Across the lower half of the frame, the two swords angle toward opposite corners, their polished blades throwing thin lines of reflected light. Embroidered seams and a dark sash at the figures' waists catch faint highlights, grounding them in the darkness. A faint blue rim traces the outer edges of the black satin, separating the fighters from the void. Across the bottom fifth, a gold-gradient serif uppercase "TITLE" spans the width in two stacked lines. In the bottom-center, between the two lines of the title, sits a small red circular emblem containing a leaping golden animal figure. In the bottom-right corner, the gold ring of the medallion curves out of the blackness behind the woman's shoulder. The lighting is dramatic and high-contrast: a hard frontal key rakes across the black satin and steel, throwing crisp specular highlights along the fabric folds and blade edges, while the red disc glows softly behind the fighters and the black surround absorbs all spill. Mirrored in a strict back-to-back symmetry, the poster sets gleaming black satin and silver steel against crimson and brushed gold on a void-black field in a slick photographic action style, radiating a fierce, heroic, and electric mood.
