So far, actress Hayley Atwell is the only confirmed cast member who is a part of ABC's upcoming "Marvel's Agent Carter" limited series.
It's expected that some of the supporting actors from either "Captain America: The First Avenger" or the "Agent Carter" Marvel One Shot short film will also be back for the eight episode series.
In a recent interview with The Telegraph, Atwell seems to have confirmed that Dominic Cooper will reprise his role as Tony Stark's father Howard Stark in the series, saying she's ready to engage in a prank war with him:
"He's incredibly naughty. So I'm going to start the pranks as early as I can. He will come up with some very good ones, too."
The possibility of Cooper's return was first indicated back in March when series co-creator Stephen McFeely revealed the Howard Stark character would recur in the 1946-set series.
Cooper's involvement still hasn't been officially confirmed yet, but it seems all but a certainty now. Whether Bradley Whitford's Agent Flynn will also return is unknown at this point.
