UPDATED: Arrow season 3 casting news
2 Fast 2 Furious and Sin City's Devon Aoki joins Arrow season 3...
UPDATE: It's been confirmed that Karl Yune (Speed Racer, Real Steel) has also joined Arrow season three in the role of Maseo Yamashiro, husband to Devon Aoki's Katana.
Arrow is supplementing its DC character stocks for season three with the addition of a new superheroine. Katana, a martial arts specialist and sometime member of the Birds of Prey, is the latest superheroine to join the Starling City gang.
Arrow's Katana, named for the soul-imbibing sword the character carries, will be played by Sin City and 2 Fast 2 Furious' Devon Aoki, no stranger to action roles.
It's being reported that the character will play a key role in Oliver Queen's Island flashbacks.
Arrow returns to The CW on Wednesdays from the 8th of October in the US.
