This is the most obvious thing to want from the show, and the one that Marvel has probably thought the most about. Clark Gregg is the only person that is confirmed to appear on the show that has been in the films. Samuel L. Jackson hasn’t heard anything about appearing, Cobie Smulders is still contractually obligated to How I Met Your Mother, and there’s been no talk about Scarlett Johansson participating in the show. But what’s stopping some of them from showing up every once in a while?
The other S.H.I.E.L.D. operatives are the easiest chances we’ve got at cameos. The heroes themselves will be a little bit harder. However, it does seem like their work beyond Marvel films is staggered to the point that a one-week excursion on a TV show is in the cards. Of all the heroes that could make an appearance though, Thor seems the least likely, the fact that he lives in outer space not withstanding. It appears Steve Rogers will be working closely with S.H.I.E.L.D. in his own sequel, but they could still show him walking down the hallway and high-five Coulson. Now with Tony Stark and Bruce Banner being best friends at the end of The Avengers, and Tony’s reputation for making things for S.H.I.E.L.D., it stands to reason the pair of them could make an appearance. Plus, it appears that Marvel is stalling the development of the solo Hulk TV series, maybe so he can show up on S.H.I.E.L.D.?
With all this talk of potential Easter Eggs and comic book connections I’ve mentioned, there are still a few I’ve left off, namely the superhuman prisons on Earth. In the Marvel Universe there are several, but The Vault, The Raft, and The Cube are probably the most famous. Even just a mention of these places is enough to make me crack a smile, but if we saw them in the show and they were housing, let’s say the Abomination, Arnim Zola, or any other number of potential villains that Marvel wants to use, it would be icing on the cake.
