The Joker(s)

The Joker, with green hair and white face paint, points a finger gun at the camera, then appears shirtless in a dimly lit room, followed by a scene of him in a dark coat walking through a sterile corridor, then tipping his hat, and finally crouching in a dark hallway. The setting shifts between a dark, industrial interior, a sterile medical or laboratory environment, and a shadowy corridor.
