One of the absolute highlights of Batman v Superman was Gal Gadot's Wonder Woman. She was almost literally a ray of light and colour in a dark grey world. And now, you can see her best moment, which also happens to be the best moment of the movie. (The video is kind of a spoiler, if you haven't seen the trailers.)
This clip surfaced on the Japanese website Eiga, presumably as part of Warner Bros.' marketing overseas. The arrival of Wonder Woman into the final battle was an actual cheer-making moment in this movie, and it's one we're happy to see over and over again.
