If you've been following the Marvel Cinematic Universe since it launched back in 2008 with Iron Man, you likely know by now that the MCU is littered with Easter Eggs throughout all of their movies. These subtle references not only tease the future Marvel adventures to come on the big screen, but also offer obscure allusions to the comics that only die-hard fans will ever pick up on.

Just before Guardians of the Galaxy hit theaters last weekend, MTV's Josh Horowitz debuted a 12-minute supercut video that breaks down all of the Easter Eggs in Marvel Phase One movies Iron Man, The Incredible Hulk, Iron Man 2, Thor, Captain America: The First Avenger and Marvel's The Avengers, along with Phase Two adventures Iron Man 3 and Thor: The Dark World.

Since Captain America: The Winter Soldier won't be available on Blu-ray and DVD until September 9, that Marvel Phase Two adventure is not included in this extensive video, but perhaps that means another Easter Egg installment will be coming in the near future, which may also include Guardians of the Galaxy.
