Cobie Smulders, best known for her roll as Robin Scherbatsky on How I Met Your Mother, played a semi-major roll on The Avengers as Agent Marie Hill. Of course, with the upcoming S.H.I.E.L.D. television show, and with a confirmed Agent Phil Coulson set to star in the show, some, like me, have asked, who else?
Well, we can (probably) add another character to the cast of S.H.I.E.L.D.: Agent Marie Hill! Though Cobie Smulders is still committed to How I Met Your Mother, there are some talks right now for her to at least star as a recurring guest throughout the show. Of course, she has said that her commitment to How I Met Your Mother won’t affect her potential S.H.I.E.L.D. appearance, so there’s a high likelihood that she will (eventually) appear in the show at some point.
