ABC's Marvel's Agents of S.H.I.E.L.D. is introducing viewers to the main characters one featurette at a time, with this week's video focusing on Agent Melinda May, played by Ming-Na Wen. The actress explains that her character, a pilot and martial arts expert, starts the series out in the S.H.I.E.L.D. offices, with no desire to go back into the field, but that changes rather quickly.
