Take a look at actress Bridget Regan as 'Dottie Underwood', the original 1940's 'Black Widow' Russian superspy, who appeared in Season 2 of "Marvel's Agent Carter", starring Hayley Atwell:
"Oh, she's a slippery bitch," said Atwell about 'Black Widow'.
"We haven't seen the last of her. 'Peggy' has male baddies that she fights, but to have someone who is physically her equal -- she's a 'Black Widow', incredibly capable and very smart -- I think that shows some balance for Peggy, like a flip side of the same coin.
