Cameos
The site reveals that Captain Marvel and Doctor Strange are nowhere to be seen in Avengers: Age of Ultron, and while there is what they call a Black Panther "tease", he too is absent. Oh, and don't go in expecting a Spider-Man reference as there's no sign of him either. The Winter Soldier also doesn't appear, but is mentioned. Heimdall meanwhile is a "vision", so him and Loki probably only appear as part of whatever Thor sees when the Scarlet Witch plays with his mind. The Falcon, Peggy Carter, and War Machine are all set to show up as well. Could Spidey appear in the mid-credits?
Linda Cardellini And Julie Delpy
Who is this actress playing? Well, according to the site, "Whedon and Feige want to keep her a surprise, and they’re absolutely right. The emotional payoff that comes from her reveal is worth the wait. I will say this: she’s no one you’ve ever heard of, not a superhero, not a villain. She’s a person. An important one. And the fact that you don’t know her is part of the reason why." So, no one from the comic books, but an extremely important character? Interesting. Julie Delpy meanwhile is playing Black Widow's instructor in a flashback to her time as a youngster in Russia.
A Character Death
Someone "important" does die in the sequel, and their passing is neither misdirection or set up for them to be resurrected. Were the rumours about Quicksilver true then? It seems that way...
That Mysterious Woman From The Trailer
Remember the woman we were all speculating about? Some thought she might be Shuri, others said Jocasta or a member of the Dora Milaje. The answer...isn't revealed in Avengers: Age of Ultron. She's been cut from the movie, and the site adds that "Thor’s whole journey to this cave is a bit of a headscratcher, which suggests a subplot that was seriously truncated." Bring on the Blu-ray!
Ulysses Klaue
Wakanda is referenced in the movie and Ultron is indeed after Vibranium. That leads him into contact with Ulysses Klaue (Andy Serkis), and arms dealer who has access to at least some of the indestructible substance. He ends up losing a hand here, setting the stage for a big return in Black Panther as the version of the character we all know from the comic books perhaps. Thoughts?
