Marvel is coming

A man in a grey t-shirt stands with hands on hips, then the scene cuts to a man in a Captain America suit looking down, followed by a blurry close-up of a woman's face, then a fast-moving blur of light and color, then a man in a blue shirt looking over his shoulder, and finally a man in a purple shirt looking directly at the camera. The setting changes from an indistinct interior to a high-tech interior, then to a warm-lit room, and finally to a modern interior with green walls.
