Well after the death of the Avengers our Beloved Agent Coulson will be resurrected for the upcoming TV series” Marvel’s Agents of S.H.I.E.L.D.” So it gave us hope that he will be returning in Avengers 2 until we heard this.
In an interview with the Associated Press, writer/director Joss Whedon says that Coulson is not present in his current draft of the sequel, Avengers: Age of Ultron, when asked if he could return for the film.
“He could. Right now it’s not something I’m pursuing because I have so much going on in ‘Avengers 2.’ Finding out that Coulson is alive would be an entire B story. And I already have too many movies. That’s better than the other thing.”
So apparently he will not be coming back just maybe he might find his way back to the Avengers 2.
Whedon elaborated on why this is the case when speaking about Samuel L. Jackson appearin in the upcoming TV series.
“But we also have the movies and we have TV and we need to make sure there’s some crossover, but not so much that people go, ‘Well, I don’t need to see that movie. I saw it on TV.’ If we do that (Marvel Studios President) Kevin Feige is going to come after me with a pitchfork.” Source: The Associated Press
