According to The Hollywood Reporter, French actress Elodie Yung is in talks to join the still-untitled GI Joe sequel as the young female ninja, Jinx.
You probably don't know Yung, whose highest-profile work so far has been in the sequel to parkour action flick District B13, but she's also going to be in The Girl With the Dragon Tattoo, and remember, you didn't know who Lee Byung-Hun was before GI Joe, either.
