The history behind the Obelisk - the MacGuffin for Agents of S.H.I.E.L.D. season two thus far - is connected to the Strategic Scientific Reserve that Peggy Carter (played again by Hayley Attwell) worked for shortly after the conclusion to WWII - something that S.H.I.E.L.D. has touched upon in multiple episodes now. In doing so, the show has begun to weave the threads linking it to the next addition to Marvel Studios' Movie and TV show universe, Agent Carter.
Agent Carter is a historical espionage "event series" about Peggy's adventures working for the SSR. The show's debut eight episodes air early next year during S.H.I.E.L.D.'s mid-season break. Tara Butters and Michele Fazekas (Reaper) are the show-runners, while both the screenwriters (Christopher Markus and Stephen McFeely) as well as directors (Joe Johnston, Anthony and Joe Russo) of the Captain America movies are likewise involved in some fashion.
As illustrated by the above TV spot as well as previously-released footage from Agent Carter, Peggy's job involves much more than going undercover (and disguising herself with blonde wigs); she also has to deal with pretty rampant sexism, in both the workplace and out in the field. Fortunately, in the latter, Peggy usually gets to punch those who look down on her at some point, which is probably why she would prefer to be out on missions whenever possible.
Other Agent Carter cast members include Dominic Cooper reprising as the younger Howard Stark, James D'Arcy (Cloud Atlas) as Stark's butler, Edwin Jarvis - who gets assigned to assist Peggy when she undertakes a secret mission for Stark - and Lyndsy Fonseca (Nikita) as Angie Martinelli, Peggy's friend - who, it seems, won't be joining Agent Carter in her many fist-fights, but will find other ways to lend Peggy a helping hand in her life/work.
The Agent Carter previews have been big on action and wordplay, but there will be more to the show than Peggy beating up baddies and fending off chauvinist remarks with her wits (which, admittedly, isn't really enough to sustain an entire mini-series). As mentioned before and detailed in the series' extended synopsis, Peggy ends up having to track down Stark's "deadliest weapons" and prevent them from falling into the wrong hands.
Agent Carter will also mark the beginning of a year that will see the release of Marvel's first Netflix series, Daredevil; combined with Agents of S.H.I.E.L.D. being very much on the upswing during its second season, and 2015 is shaping up to be a pretty good time, as far as Marvel entertainment on the small screen is concerned.
Agent Carter premieres on Tuesday, January 6th, 2015 on ABC.
