Marvel Phase 1 Guide: the incredible hulk
Viewing Order Placement
The Incredible Hulk, Iron Man 2, and Thor all take place roughly during the same week, a surprising fact to most viewers who aren't paying close attention, especially because it is never explicitly said in the films themselves.
So, out of these three movies, why does The Incredible Hulk come first? A few reasons. It was released in theaters long before the others. Also, a majority of the film does take place before both Iron Man 2 and Thor with one notable exception: the final scene before the credits takes place after Iron Man 2, but we'll get to that later.
References and Easter Eggs
Opening Credits: The opening credits sequence features several easter eggs, including references to Stark Industries, Nick Fury, and S.H.I.E.L.D.
Super Soldiers: The serum used on Emil Blonsky to give him enhanced strength and agility is based on the super soldier serum that created Captain America during World War II.
Mr. Harrington: Credited simply as Computer Nerd, Martin Starr cameos as a student at Culver University. He will go on to be a teacher at the Midtown School of Science and Technology as seen in Spider-Man: Homecoming and Spider-Man: Far From Home.
S.H.I.E.L.D. Presence: The S.H.I.E.L.D. logo can be seen on a computer used by Bruce Banner.
Stark’s Team: Tony Stark appears at the end of the film to speak with General Ross about a team that's being put together, a reference to the Avengers Initiative. The scene is revisited and further explained in the short film, The Consultant.
