2. Cameos
As we have noted before, Whedon has a wide stable of actors that he returns to time and again. As yet, we have not heard whether any of them will be appearing in S.H.I.E.L.D. (although Sean Maher and Nathan Fillion have all but confirmed that they won’t be in various interviews). Still, even the short-lived Firefly saw several Buffy and Angel alums popping up and I wouldn’t be surprised to see any of the ten actors we mentioned or any of the ones we didn’t on the show.
Personally, I’m still holding out for Fillion as Hank Pym, but I would settle for James Marsters as just about anything.
