Cinematic Typography Poster

A minimalist cinematic poster on a tall vertical canvas with an off-white textured paper background and a dark matte stage platform at the bottom, dominated by giant condensed black sans-serif letters spelling {argument name="main title" default="SAM ALTMAN"} across nearly the full height of the composition, with the first word stacked above and overlapping the second. Replace one central vertical letterform with a glowing open doorway, outlined in warm orange-red light, revealing a bright sunrise sky and a distant cityscape beyond. On the stage, place 1 lone adult man seen from behind in three-quarter profile, walking toward the doorway, wearing a dark crewneck sweater, dark pants, and light sneakers, with realistic proportions and subtle dramatic rim lighting. To the upper right of the typography, add 3 small lines of spaced uppercase text reading {argument name="tagline line 1" default="AI."}, {argument name="tagline line 2" default="POWER."}, and {argument name="tagline line 3" default="POSSIBILITY."}. In the lower left corner, add 1 small orange credit line reading {argument name="credit text" default="OPENAI CEO"}. Use strong scale contrast, lots of negative space, editorial magazine-cover styling, clean modern layout, muted neutral tones with one warm orange accent, realistic lighting, subtle film grain, and a sophisticated futuristic mood.
