collage poster design — Oversized title, Multi-line title, Serif lettering

A painted movie poster of two large floating heads of adult men above a red title and an undersea battle scene, set against bright blue ocean waters under a clear sky. Across the top half of the frame, the open sea glows in vivid cobalt blue, with thin white clouds streaking across the upper-left corner. On the left side of the frame, the larger of the two heads belongs to an adult man with wavy silver-gray hair swept back from a broad forehead, his blue-gray eyes fixed on the viewer with an intense expression. His weathered skin shows fine lines at the corners of his eyes, and a simple dark earring glints at his left ear; he wears a loose brown garment at the shoulders. On the right side of the frame, the second head is an adult man with a full dark beard and mustache, wearing a dark navy captain's cap with a gold band and a circular silver emblem. His dark eyes look off toward the right edge of the frame, and he wears a dark high-collared coat over a white shirt. Between and behind the two heads, their edges dissolve softly into the blue background in a classic floating-head collage style. In the upper-right corner of the frame, the blue sky deepens to a richer navy tone. Across the center of the frame, a large title ("TITLE") in bold red serif lettering spans two lines, the upper line led by oversized numerals and the lower line stretching the full width of the poster. Beneath the title, a long dark Victorian-style submarine with a spiked, riveted hull cruises from the lower-left toward the right, its single glowing porthole catching the light. The vessel is gripped by the curling tentacles of a giant blue squid, whose suckered arms wrap around the hull and trail through the water. White foam bursts around the struggling submarine where the tentacles thrash near the lower-left corner. Small whitecaps texture the water where the submarine's wake spreads to the right. Along the bottom edge of the frame, a purple-blue coral reef spreads in dark textured mounds, dotted with small pale polyps. A lone sea urchin with dark spines sits on the reef near the bottom center. In the lower-right corner, the water lightens to a soft glowing turquoise where sunlight filters down. The lighting is bright and even like a sunlit afternoon at sea, with soft highlights on the men's faces, crisp sparkle on the water's surface, and gentle blue gradients deepening toward the bottom of the frame. No other text or credits appear on the poster besides the central red title. The painted rendering is smooth and idealized, with soft airbrushed transitions on the skin and dramatic detail in the submarine's metalwork. Overall, the poster's symmetrical floating-head composition balances the two looming portraits against the action tableau below, rendered in a classic mid-century painted adventure style with a saturated azure-and-crimson palette and a mood of grand romantic peril.
