Wonder Woman Ares. With Gal Gadot, Chris Pine, Robin Wright, Lucy Davis. It is the fourth installment in the DC Extended Universe (DCEU).
Well, I think the answer was in movie itself, when Ares explains that he is not god of war, rather he creates the situations and whisper into ears of people and people create wars. Ares is a recurring antagonist of DC's flagship superheroine Wonder Woman. Directed by Patty Jenkins from a screenplay by Allan Heinberg and a story by Heinberg, Zack.
During most of the Golden Age, Silver Age, and Bronze Age, Ares was called Mars and was one.
He was portrayed by David Thewlis.
When a pilot crashes and tells of conflict in the outside world, Diana, an Amazonian warrior in training, leaves home to fight a war, discovering her full powers and true destiny. And now that God of war is gone, Earth should be war free. This will be a great addition to your Wonder Woman Collection!
