6) Bridget Regan – Dottie Underwood
It’s a testament to the entertainment value of the character usually known as Dottie Underwood that, though she was only the secondary antagonist of Agent Carter’s first season, she emerged as one of the show’s best characters.
Initially presented as a ditzy neighbour of Peggy’s, it later becomes clear that she is in fact a Black Widow (just not the Scarlet Johansson one). An insane, amoral assassin with a serious obsession with Peggy, Dottie was a cool enough character on the page alone, but Regan had a sparky chemistry with Hayley Atwell that really made Dottie come to life.
It was a real shame that season two under-utilized her to the extent that it did. It would have been great for the third season to have forced Peggy and Dottie forced to work together permanently, promoting Regan to series regular. Alas, that’s never going to happen now.
Don’t mind us, we’re just going to go cry in a corner.
