Agent Carter has finally begun filling out its cast. Dollhouse alum Enver Gjokaj and One Tree Hill star Chad Michael Murray have joined the cast as series regulars, EW has confirmed.

Carter stars Captain America’s Hayley Atwell as the titular agent who deals with being marginalized once WWII ends. In the wake of losing her love, Steve Rogers, Carter navigates the world of the SSR, the forebear to what we now know as S.H.I.E.L.D. Murray will play SSR Agent Jack Thompson, while Gjokaj will play Agent Daniel Sousa, both of whom Peggy meets in New York.

Marvel’s new series will air in the gap between the first and second halves of Agents of S.H.I.E.L.D.’s sophomore run.
