Tao Okamoto might not be a household name, but the Japanese actress and model can already lay claim to having nabbed roles in movies based on both Marvel and DC characters, starting with 2013's The Wolverine. She played Mariko Yashida in Fox's Marvel offering - the daughter of Shingen Yashida AKA the Silver Samurai, who was the movie's main villain. She has also completed filming for next year's highly-anticipated DC blockbuster Batman v Superman: Dawn Of Justice. She will portray Mercy Graves in that movie - Graves being the assistant and bodyguard to Jesse Eisenberg's Lex Luthor in the comic books - but little is known about how prominent her role will be or exactly what it will entail.
