Men en tv-show med Coulson diskuterades innan filmen kom:
“We all love Clark Gregg, there’s no doubt about that,” Whedon said. “From before we made ‘The Avengers,’ we discussed whether there was a way for him to be a part of the Marvel Universe, perhaps a part of a TV show even after his death. … The fact of the matter is, as much as we love him, now that I’m really running Marvel, I like to keep a type of artistic integrity, which means we don’t stretch the bounds of reality.”
“There was never going to be a ‘S.H.I.E.L.D.’ show without Agent Phil Coulson!” said Feige - CBR
Så visste de inte om showen kommer eller inte när de filmade The Avengers men de ville ha Coulson från början och det var därför de återupplivade honom för showen.
