ABC and Joss Whedon have cast two more actors in their upcoming Marvel TV series S.H.I.E.L.D. Those actors are Elizabeth Henstridge (Shelter) and Iain De Caestecker (The Fades, Young James Harriot).
According to THR, Henstridge will play a character named Agent Gemma Simmons described as a science whiz, and De Caestecker is set to play Agent Leo Fitz, a technology guru. "The duo spend all their time together -- mostly bickering -- and are masters at a remarkably young age of their respective fields."
They join the previously cast Ming-Na, who plays Agent Melinda May a top-notch pilot and weapons expert, and of course Clark Gregg, who is reprising his role as Agent Phil Coulson.
The story will revolve around the activities of the top-secret S.H.I.E.L.D espionage organization featured in The Avengers. Whedon is tentatively set to direct the pilot for the series that he will write along side his brother Jed Whedon and Maurissa Tancharoen.
