Cobie Smulders will appear on "Marvels Agents of S.H.I.E.L.D."
The "How I Met Your Mother" star will reprise her role as Agent Maria Hill. "I wanted very much to have Cobie in the pilot because as much as anyone else, she is S.H.I.E.L.D.," says Joss Whedon. "She's cool and commanding, and has the dry humor that plays so well with Clark's. Also, if she's in it, I get to hang out with Cobie."
