A retro vintage collage design of film Joker (2019). The atmosphere should be dark and cinematic, with textures like torn paper, halftone dots, and grainy vintage poster effects. Neon accents of maroon and green glow throughout the collage, symbolizing chaos and madness. The overall style is nostalgic 80s/90s poster art, bold, layered, and chaotic but balanced, like an underground street collage.
