There is only one Agent Carter – actress Hayley Atwell – and she will bring the character to the small screen for the Marvel spin-off show of the same name. Howard Stark, on the other hand, has so far been played by no less than three actors. Gerald Sanders portrayed him first in Iron Man, but then transformed into John Slattery in Iron Man 2. His most recent guise was in the shape of British actor, Dominic Cooper, however, who filled the role in both Captain America: The First Avenger, and in the Marvel One-Shot Agent Carter, that essentially served as an early pilot for the forthcoming series.
