According to The Avengers director Joss Whedon the releationship between Agent Coulson and Captain America is the funniest relationship in the movie. He expalins this relationship, and how the scenes bewtween these two character are some of his favorite scenes in the movie.
Coulson is the face of S.H.I.E.L.D in a way that Nick Fury isn’t. Nick Fury stays in the background pulling the strings, while Coulson is the guy in the trenches alongside ‘The Avengers.’ His relationship with Steve Rogers is one of my favorites. There are so many characters in this film with a dry wit, so I wanted to find some other dynamic Coulson could have with Captain America and it hit me, ‘Oh my god, he’s a fan boy!’ Giving him a man crush on Captain America not only lent itself to some of the funniest scenes, but also established the type of relationship they had, which led to the whole trading card run in the scene, which is possibly my favorite thing in the movie.
What a brilliantly hilarious idea! I can easily see Coulson having a hard fanboy "man crush" on Steve Rogers! It really fits his character perfectly, and there's no doubt that it brought an awesomely fun dynamic to the movie. Greg Clark, who plays Coulson in the Marvel films, had this to say about his character,
What I love about Coulson is how he has evolved from what seemed like an annoying bureaucrat pestering Tony Stark for an interview in ‘Iron Man.’ As the Marvel film universe has expanded it’s been a great thrill to see him become a much more formidable force who’s kind of hiding in plain sight. Every time I get a Marvel script, I’m very excited to find out what new layers to his character and duties are revealed and it certainly has culminated with ‘The Avengers,’ where he is heavily involved with trying to pull the team together.
The Avengers initiative has not necessarily been accepted by the World Security Council and is looked at with some great suspicion. The Super Heroes are viewed as dangerous and uncontrollable and I don’t think anybody, including Nick Fury, is fully convinced yet that The Hulk and Thor are good people to have around, based on what has gone down in the past. So in the time leading up to The Avengers, a major focus of S.H.I.E.L.D. is about developing the Tesseract and finding out a way to harness and use its vast power.
Everything I've seen and heard about this movie is flat out fantastic. I have no doubt that it will deliver the fans everything we want and hope to see. After this movie, Joss Whedon will be one of the most sought out film directors in Hollywood.
