Captain Marvel Website: 12 Secrets, References & Easter Eggs EXPLAINED
8. The Collector Of Cards
Not all of the message board usernames are immediately obvious as references to anyone in particular. Some of them might be personal nods by the site's developers for instance and none of them refer to actual Twitter accounts (well, not intentionally - most of them actually ARE taken on Twitter, but not to linked accounts - one of them is actually linked to a torrenting site, rather unfortunately for Marvel).
But one of the usernames is a big, slightly obscure reference. A user by the name of THE_COLLECTOR_OF_CARDS posts one of the film's new tag-lines "Higher. Further. Faster." which hasn't at all been borrowed from Daft Punk. And when you think about who in the Marvel Universe might call themselves that, there's only one answer...
That person is Phil Coulson, who literally collected Captain America cards in one of the key plot-points in The Avengers. He's also set to return to the big screen MCU in Captain Marvel, so that's one of the smartest deep references on the site.
