Marvel's 'Agent Carter' Adds A New 'Avengers' Link

James D'Arcy is a vision as Edwin Jarvis!

Marvel's "Agent Carter," starring Hayley Atwell as "Captain America" leading lady Peggy Carter, just added a big-name character to its cast, connecting the show to the "Avengers" franchise in some very interesting ways.

According to Marvel.com, James D'Arcy ("Cloud Atlas") has joined the cast of "Agent Carter" as Edwin Jarvis. Longtime Marvel readers know Jarvis as the Stark family butler, and a reliable caretaker of the Avengers. (For the uninitiated, think of it this way: Jarvis is to Iron Man as Alfred is to Batman.)

Described by Marvel.com as "Howard Stark's butler and an unexpected ally to Peggy Carter," Jarvis' involvement in "Agent Carter" all but confirms that Howard himself will appear on the show. Marvel has yet to make that news official, but, come on. This train isn't moving without Dominic Cooper on board, at least as a guest star.

Here's another idea worth chewing on. In the Marvel movies, Tony Stark relies on an A.I. system called J.A.R.V.I.S., voiced by Paul Bettany, the same man who will play avenging android Vision in "Avengers: Age of Ultron." It's long been assumed that Vision's existence will owe no small part to the J.A.R.V.I.S. system; why else cast Bettany in the role?

Now, we know that there's a Jarvis predating J.A.R.V.I.S. — but he's not played by Bettany. Could that mean multiple Jarvises? Will the Edwin Jarvis of "Agent Carter" have a son, one who looks like a young Paul Bettany, someone who could grow up to become Tony Stark's pal, and the basis of the J.A.R.V.I.S. technology? Why else have a different actor playing Edwin Jarvis and Vision?

However it shakes out, "Agent Carter" adding an actor of D'Arcy's caliber to play someone as significant in the Marvel lore as Jarvis is an exciting sign for an exciting project. We'll keep you posted with more casting news as it's announced.
