May I direct your attention to the very end of the Avengers film, pre-credits, where Hill is calmly asking Director Fury about the Avengers re-assembling? Great. There is a part afterwards where the camera pans out along the bridge of the helicarrier.
Now, when I was watching this low-quality version of the film on my laptop, I noticed this man. Just Saturday, I went to the theatre to get a more up-close look at this man.
Guess what. It’s Coulson.
You’re welcome. :|
