Max & Anna: A Heartwarming Pixar Trailer

Create a heartwarming 15-20 second cinematic trailer intro in vibrant Pixar animation style, with rich colors, expressive characters, detailed fur and textures, soft volumetric lighting, and a whimsical orchestral score swelling in the background.

Open with a wide establishing shot of a sunny suburban park in autumn: golden leaves falling gently, a lush green lawn, distant trees with warm sunlight filtering through.

Camera slowly pushes in to reveal Max, an adorable fluffy golden retriever dog with big expressive eyes, playful ears, and a wagging tail, curiously sniffing around the base of an old oak tree.

Suddenly, Anna, a cute energetic red squirrel with shiny fur, bright eyes, fluffy tail, and a mischievous personality, peeks out from behind the trunk holding a large acorn.

Max looks up in surprise, tilts his head, and lets out a friendly bark. Anna freezes for a moment, then drops the acorn which rolls toward Max.
Max gently noses the acorn back toward Anna. She hesitates, then cautiously climbs down the tree.
They circle each other playfully — Max wagging his tail excitedly, Anna chattering happily.

Cut to a close-up as Anna climbs onto Max's back, and they both look toward the camera with joyful expressions.
Max gives a happy bark, Anna raises her tiny paw in triumph, and they run off together across the park as leaves swirl around them.

End with a gentle pull-back wide shot of the park, the title text fading in elegantly: 'Max & Anna'
Cinematic camera movements, emotional storytelling, highly detailed Pixar-quality rendering, warm and uplifting mood, perfect for a family animated trailer intro.
