The Avengers star Clark Gregg has discussed his character's crucial involvement in the superhero epic.
Speaking at the movie's UK press conference, Gregg admitted that he had mixed emotions about the fate of his SHIELD operative Phil Coulson.

Gregg said that he found out about Coulson's fate before taking part in the Thor panel at Comic-Con.
The actor recalled: "Joss Whedon comes over and said, 'Coulson's going to have a big part in The Avengers, can I introduce you as part of the cast?' It was officially the shortest decision-making period I've ever needed!
"Then there was an ominous call from Marvel about how important Coulson's role would be in this film. I loved playing this guy a lot, and when I got Joss's script it was one of the best days I've had as an actor.
"It's been a chain letter - different directors get this character and reveal another facet [to him], always entertaining.
"What Joss did, I thought, was magnificent. Because it's in the Marvel universe, I think of it as an extension rather than a definite resolution."
The Avengers is released in UK cinemas on April 26 (under the title Marvel Avengers Assemble) and on May 4 in the US.
