World War II is over, but superspy Peggy Carter is still fighting the good fight — and she's looking pretty damn good while doing it. ABC's lushly produced, seven-episode action-adventure series Marvel's Agent Carter, set in 1946, will be bringing some old-style Hollywood glamour to primetime. Leading lady Hayley Atwell wholeheartedly approves.

"This series is such a film-noir feast for the eyes that I come to work an hour early just to watch," says the British actress, who first played Carter in the 2011 movie blockbuster Marvel's Captain America: The First Avenger. "Despite all the chaos of the war years, people had great style — the guys so elegant and gentlemanlike, the women so beautiful and well turned out with their cinched waists, pencil skirts, pin curls, and red lips. To act in this time period is absolute heaven."

Peggy, however, is in her own kind of hell. She had been a fierce and brilliant secret agent for the Allies' Strategic Scientific Reserve during the war — in fact, she will one day be integral to the formation of S.H.I.E.L.D. and serve as its first cohead. But with the Nazis defeated, she's been demoted to an SSR desk job. "Peggy is making coffee for the men and taking their lunch orders," says Atwell. "She's feeling incredibly wasted, disrespected, and frustrated."

She's also in deep mourning for her love, Steve Rogers (aka Captain America), who is believed to have died in a plane crash. To bury her grief and get back some self-respect, Peggy decides to moonlight for her old friend, industrialist Howard Stark (Dominic Cooper), who is being framed for selling weapons of mass destruction to the enemy and is wanted by the SSR.

"That has Peggy leading a triple life," says series cocreator/executive producer Christopher Markus. "Her friends and neighbors think she works for the telephone company, and the SSR has no idea she's working undercover for Stark to clear his name." But can she truly trust her new employer? Stark, future father of Tony "Iron Man" Stark, is "a known rapscallion," says Markus. "He's not a traitor to his country, but that doesn't mean he won't end up on the wrong side of the law. He has his secrets."

Markus and cocreator Stephen McFeely wrote the scripts for The First Avenger and modern-day sequel Marvel's Captain America: The Winter Soldier, which featured an elderly Peggy on her deathbed. "We're the first to admit we didn't give the character that much to do in the films," McFeely says. "It's Hayley's incredible performance that made people want to know more about Agent Carter. We owe this series all to her

Marvel's Agent Carter's two-hour premiere airs Tuesday, Jan. 6 at 8/7c on ABC.
