SCENE PROMPTS (DO NOT CHANGE ANY WORDING EXCEPT CHARACTER NAMES, AGES, AND AUTOMATIC HOUSE ADAPTATION):

Scene 1:

Close-up cinematic shot of an elderly {SUPPORTING_CHARACTER}’s finger pressing a doorbell at the front door of {MAIN_CHARACTER}’s cartoon-accurate iconic house at night. Only his long, slender finger is visible, slightly wrinkled with age. The finger hesitates briefly, then gently presses the bell. Warm porch light contrasts with the dark nighttime surroundings, soft Disney-style 3D rendering, shallow depth of field, emotional anticipation mood, subtle hand tremble showing nervousness, cinematic realism.  

Dialogue ({SUPPORTING_CHARACTER}, softly whispered):  

“…I’ve stood here a thousand times… just not brave enough to knock.”

Scene 2:

Medium shot of elderly {MAIN_CHARACTER} sitting comfortably in an armchair inside his cartoon-accurate iconic house living room at night, relaxed while watching TV. The room is softly lit by the television glow and warm interior lights. Suddenly, the doorbell sound startles him. His eyes widen slightly, eyebrows lift, and his body reacts with a small jolt. He slowly turns his head toward the door with curiosity and surprise. Disney-style 3D animation, soft nighttime lighting, expressive facial animation, cozy and nostalgic atmosphere.  

Dialogue ({MAIN_CHARACTER}, quietly):  

“…That sound… I haven’t heard it like that in years.”

Scene 3:

Front-facing medium shot of elderly {MAIN_CHARACTER} standing behind his opened front door inside his cartoon-accurate iconic house at night. Cool moonlight from outside blends with warm indoor lighting. He freezes in place as he sees someone outside. His expression mixes shock, sadness, and deep happiness; his eyes shimmer with tears, slightly watery and reflective. His mouth trembles into a soft smile. Disney 3D emotional character acting, detailed facial expressions, warm cinematic lighting, heartfelt nighttime reunion moment.  

Dialogue ({MAIN_CHARACTER}, voice breaking):  

“…You look just like you did… only time is older now.”

Scene 4 (VIDEO PROMPT):

Elderly {SUPPORTING_CHARACTER}, medium close-up video shot, standing at the open doorway of {MAIN_CHARACTER}’s cartoon-accurate iconic house at night.  

Camera is positioned INSIDE the house, looking outward through the open door. {SUPPORTING_CHARACTER} is facing inward toward {MAIN_CHARACTER}, directly toward the camera viewpoint.  

Subtle cinematic motion: the camera performs a very slow, gentle push-in toward {SUPPORTING_CHARACTER}. His chest rises and falls with quiet breathing, his eyes blink slowly, and a faint tremble passes through his eyelids as tears gather.  

His expression is deeply emotional: tired eyes, slightly drooping eyelids, watery eyes filled with tears, a subtle sad but relieved smile. Wrinkles on his forehead and face are clearly visible, emphasizing age and emotion.  

Soft warm interior light from inside the house illuminates his face, creating gentle highlights and shadows. Outside background shows a softly blurred nighttime environment consistent with the character’s world, faint ambient movement, soft blue tones.  

Disney-style 3D character design, cinematic lighting, emotional realism, shallow depth of field, slow natural motion, nostalgic and heartfelt mood.  

Dialogue ({SUPPORTING_CHARACTER}, gentle and sincere):  

“I kept walking forward… but every memory kept leading me back here.”

Scene 5:

Wide emotional shot of elderly {MAIN_CHARACTER} and elderly {SUPPORTING_CHARACTER} embracing each other tightly at the entrance of the cartoon-accurate iconic house at night. Warm interior light spills out behind them, contrasting with the dark, peaceful night outside. {MAIN_CHARACTER}’s arms wrap warmly around {SUPPORTING_CHARACTER}, while {SUPPORTING_CHARACTER} slowly returns the hug with visible emotion. Their bodies lean together, conveying relief, forgiveness, and long-held longing. Tears gently fall, but both smile softly. Disney-Pixar-inspired 3D animation, smooth motion, soft nighttime lighting, emotional climax, wholesome and nostalgic ending.  

Dialogue ({MAIN_CHARACTER}, barely a whisper):  

“…No matter how long it took… this was always home.”
