In the video, we see Robert Downey Jr. playing the character of Tony Stark, who is dressed in a suit and tie. He is standing in a room with a modern design, and he is talking to someone off-camera. He makes a hand gesture as if he is explaining something. Then, Chris Hemsworth, playing the character of Thor, enters the frame. He is wearing a red cape and has long blonde hair. He looks surprised to see Tony and says something to him.
