Edwin Jarvis
Tony and Steve’s trip back to the S.H.I.E.L.D. base Camp Lehigh in 1970 brings back a few familiar faces – the aforementioned Howard Stark, Hank Pym and Peggy Carter (a preview of her more significant cameo later on). The most surprising walk-on in this sequence, though, has to be Edwin Jarvis, if only because much of the audience probably won’t realize who he is.
When Tony hugs Howard goodbye, the elder Stark is confused by the younger man’s affection and asks his driver if he’s ever met him before. The non-committal Jarvis comments that he knows a lot of people and the pair get into the car. It’s a tiny scene in the grand scheme of things, but it actually marks a huge deal for the MCU as a whole.
James D’arcy’s Jarvis – yes, the butler is where Tony got the name for his A.I. from – previously featured on Agent Carter. This means that Jarvis has the honor of being the very first character to make the jump from the TV side of the Marvel universe over to the film side. It’s a testament to the breadth and popularity of the MCU that the filmmakers now trust fans to recognize a character we haven’t seen on the small screen since 2016.
