Create a high-quality 8K UHD image of the Iron Man (2008) movie poster. The poster should feature Iron Man in his iconic Mark III armor, flying upward in a dynamic pose with glowing repulsors and an illuminated arc reactor. Include Tony Stark's unmasked, confident face in the foreground, with Pepper Potts elegantly positioned in the background. Add a faint image of the Iron Monger suit in the backdrop to create dramatic tension. Use a futuristic industrial background with fiery oranges, smoky grays, and blue highlights for glowing HUD and tech elements. Emphasize hyper-realistic textures for Iron Man’s armor, enhanced by cinematic lighting and reflections. Include the bold title "Iron Man" in metallic gold font, along with the tagline "Heroes aren't born. They're built." Ensure the overall design is polished and professional, capturing the essence of the original movie poster.
