Avengers: Age of Ultron — LEGO Sets Give Scene Clues
Possible Spoilers Ahead — You've Been Warned
I downloaded the PDF of the LEGO Germany catalog last night. It's 180mb and has over 160 pages. I extracted the images unencumbered with text. With a translation into English via io9, these LEGO sets give us some clues about how sequences we've seen in the trailer might be playing out.
Burglary At The Hydra Fortress
Looks like Captain America steals Loki's staff from Hydra. Must be the place where Cap was kicking the door in.
Duel With Hydra
I have a feeling that this is part of the burglary of Hydra.
Raid On The Avengers Tower
Early Ultron drones have Loki's staff. Perhaps the presence of the stolen staff corrupts Ultron, making him evil.
The Avengers Quinjet Chase
The Vision in minifig form working with the rest of the team.
Iron Man vs Ultron
Despite the name of the LEGO set, Ultron is not included, but two drones are.
Hulkbuster Rescue Mission
Includes the real Ultron. Based on the trailer, it doesn't seem like the Hulkbuster is rescuing the Hulk. Either the Scarlet Witch is controlling the Hulk or Ultron is controlling the Hulkbuster. This sequence might be the best part of the movie.
