I've only watched a little of this show, not even a full episode. But I thought this was interesting and deserved some exposure here.

Funny, I thought there already was a thread on this show here.

Devon Aoki Joins CW’s ‘Arrow’
By THE DEADLINE TEAM | Tuesday July 1, 2014 @ 1:40pm PDT



Devon Aoki has landed a major recurring guest role on the hit CW drama Arrow from Warner Bros TV. Aoki will play Tatsu Yamashiro, a character that first appeared in the Green Arrow origin series graphic novels published by DC Comics. She is a Japanese martial arts expert who wields a deadly sword, a blade from which her codename Katana is derived. In Arrow, Tatsu will be one of Oliver’s mentors in the flashbacks and a critical influence on his journey to eventually become The Arrow of present day. Aoki, repped by Schiffco, appeared in features including 2 Fast 2 Furious, Sin City, D.E.B.S. and War.

Deadline brings word this afternoon that actress Devon Aoki has been cast as Tatsu Yamashiro, aka Katana, for the upcoming third season of "Arrow"!

A skilled martial artist, Katana gets her name form the deadly sword she wields which contains the souls of everyone she has killed, including her late husband. It's unclear if this supernatural angle will manifest itself in the character in the series, but we do know that she will be important to Oliver's flashback sequences in the upcoming season. In the comics, the character is closely associated not only with the Birds of Prey but also Batman's The Outsiders.

This isn't the only sword-bearing comic character Aoki has played either, as she took on the role of Miho for the original Sin City in 2005.

"Arrow" airs Wednesdays at 8 P.M. ET/PT on The CW with the new season set to premiere on October 8th.
