According to itsjustmovies.com it seems unlikely. Clark Gregg who played Coulson in “The Avengers” indicates he would be interested in reprising the role in S.H.I.E.L.D. But with his character “on a slab” he is disapointed it probably won’t happen.
Gregg told Movies.com of his disappointment and frustration when he heard about the planned television series: “You know what, that was the moment when I went ‘Great, they’re doing the S.H.I.E.L.D. TV show and I’m on a slab’.
“I don’t know if we’ll see Agent Coulson again, but I certainly do his voice in their animated series, The Ultimate Spider-Man, and you never know, there may be a flashback or something sometime.
“I really hit it off with those guys [at Marvel], and I’ve talked to them lately about some ways I can continue to work with them, perhaps as a writer or director.”
Do you think the Whedon clan could find a believable way of bringing Coulson back?
