Fans of Marvel's Cinematic Universe were already given a glimpse of what to expect once Peggy Carter (Hayley Atwell) landed her very own series, but now Agents of S.H.I.E.L.D. cameos have given way to Agent Carter - and a brand new chapter of Marvel's expansive fiction has begun.
Unsurprisingly, the two-part premiere of the eight-part series was packed with plenty of seeds that may or may not grow into larger story lines for either Marvel's TV or movie universe. Those who have studied the finer points of every Marvel film released to this point may have caught most, but we're sure that a handful passed by even the most eagle-eyed viewer.
Needless to say, there will be plenty of minor spoilers concerning the future villains or plot twists in our list of Agent Carter Easter Eggs You Might Have Missed, so read at your own risk.
It didn't take long for Daniel Sousa (Enver Gjokaj) to prove he saw Peggy Carter as more than just a pretty face, but there's a good chance that audiences saw something familiar in the actor as well. That's likely due to the Dollhouse alum's brief appearance opposite Captain America as an NYPD officer during The Avengers' climactic battle.
When the series was revealed to be bringing Howard Stark (Dominic Cooper) back from his role in Captain America: The First Avenger, the writers didn't stop there. Joining Howard in his efforts to get the future S.H.I.E.L.D. off the ground is his trusted butler, Edwin Jarvis (James D'Arcy). And if the name sounds familiar, it should.
When the Iron Man film series introduced Tony's AI butler/confidant/partner-in-crime going by the name J.A.R.V.I.S. - an acronym for 'Just a Rather Very Intelligent System' - comic fans saw it as a clear nod to Edwin Jarvis, Tony's boyhood butler. Now that Jarvis is confirmed to have pre-dated the system, it seems Tony is more sentimental than he lets on.
Lucky Star Cab Company
As Peggy flees from the scene of her safe-cracking caper, her pursuer catches a glimpse of her making an exit, stepping into a brightly-colored taxi cab. A closer look reveals the cab in question to bear the Lucky Star Cab Company logo: previously seen during the Captain America: First Avenger action sequence when Steve first discovers his powers.
After appearing in multiple Iron Man films as the go-to oil company for Marvel's film universe, Roxxon once again surfaces in the 1940s as not just the sponsor of the 'Captain America Adventure' radio program, but losing an entire refinery to Howard Stark's stolen weaponry. Though the corporation was pivotal in founding S.H.I.E.L.D., they would later turn their power to more nefarious plots - including a role in the deaths of Howard and Maria Stark.
The identity of the Soviet scientist consulted by Peggy and Jarvis was spoiled ahead of the show's premiere, but the connection remains one worth noting. The scientist in question is Anton Vanko, a comic book character who began as a colleague of Stark's before returning home to one day craft his own suit of armor as the villainous 'Crimson Dynamo.'
But Marvel already modified that origin story for Iron Man 2, in which Anton Vanko sent his son, Ivan (Mickey Rourke) on a path to vengeance as the armored 'Whiplash.' If we were to bet on the outcome, expect Anton and Howard to part ways on less than friendly terms.
