- The infographic mentions Fury's Big Week - this was an eight issue comic book series by Marvel that tried to tie the movies together. It showed Nick Fury's attempts to complete the Avengers Initiative - bringing all the superheroes together. Some of the events in the infographic did not appear in a movie, only in the comic book. Fury's Big Week is available to purchase from Comixology.
- The artifact known as the Tesseract is a major plot point in The Avengers. The Tesseract is what powered the Red Skull's weapons in Captain America: TFA and what Loki needs to conquer our world.
- Most of the events in Iron Man 2, The Incredible Hulk, Thor, and the last five minutes of Captain America: TFA, occurred during the same week. This shows why it was critical for Marvel to have Samuel L. Jackson signed on for all of these flicks. This timeline also illustrates the meticulous planning that must have gone into all of these films in order for The Avengers to make sense chronologically.
