The continuity between Marvel’s films and Marvel’s TV shows has remained shaky at best, and many on the film side of things continue to insist that Coulson is still very much dead — despite his apparent resurrection in Agents of S.H.I.E.L.D. For now, it looks like we’re going to have to take solace knowing that Clark Gregg is still out there in flying his Marvel flag.
Clark Gregg’s tweet helped to clear up why he wasn’t present for the class photo (mainly because other “dead” characters were there as well), but it didn’t answer the question of whether or not we will ever see Phil Coulson in a Marvel movie ever again.
