English actor James D'Arcy has been cast as Edwin Jarvis in the upcoming Agent Carter TV series. Jarvis is Howard Stark's butler, and will be a recurring ally to Peggy Carter.
Jarvis is an iconic character in the Avengers comics as Tony Stark's butler in the Avengers Mansion, but in the Marvel Cinematic Universe, Jarvis is J.A.R.V.I.S., an artificial intelligence created by Tony Stark, and it's now revealed that Stark named the AI in honor of his father's butler.
D'Arcy joins Hayley Atwell in the series, which also includes Enver Gjokaj and Chad Michael Murray. Dominic Cooper, who played Howard Stark in the movies, has yet to officially confirm his involvement with the show.
