It looks like Ming-Na Wen (ER) will be joining Clark Gregg (The Avengers) as a lead role in ABC's television series, Marvel's S.H.I.E.L.D.  We previously reported that Gregg would return to the franchise's famous security organization as Agent Coulson, albeit on the small screen this time.  Wen will play Agent Melinda May, an ace pilot and weapons expert who often goes beyond the call of duty, but is showing signs of mental fatigue due to her combat experiences. With Joss Whedon on board to write the co-write the pilot script, you can expect a powerful and dynamic character in May and a more-than-capable actor to bring her to life in Wen.  Hit the jump for more.ming-na-wen-shield-seriesDeadline reports that Wen will join Whedon's TV series, Marvel's S.H.I.E.L.D. on ABC.  Her character sounds like it fits the bill of Agent Althea Rice from the previously reported character descriptions:

Agent Althea Rice –  Also known as “The Calvary,” this hard-core soldier has crazy skills when it comes to weapons and being a pilot. But her experiences have left her very quiet and a little damaged.

We know Coulson will return to the show as well, which leaves four more roles to fill, if those descriptions still hold true today.  Whedon is co-writing the pilot script with his brother Jed Whedon and Maurissa Tancharoen, who will all executive produce along with Jeffrey Bell and Marvel TV’s Jeph Loeb.

Wen's career spans both live-action and voice roles, with some of her most recognized work being in television (except for the fans who may know her as Chun-Li from 1994's Street Fighter). She's also recently starred in series SGU Stargate Universe and Eureka.
