This is clearly a rumor BUT if it does happen to be true, THIS IS A SPOILER. SO PLEASE BE AWARE. READ AT YOUR OWN RISK.
So apparently the opening 20 minutes of Avengers: Age of Ultron has been leaked. This is the description of the rumored opening:
The movie opens immediately following the stinger sequence featuring Baron Von Strucker, Quicksilver (Aaron Taylor-Johnson) and Scarlet Witch (Elizabeth Olsen)
Von Strucker, Scarlet Witch, and Quicksilver have a massive battle versus The Avengers
Von Strucker has a Chitauri ship and weapons
The Avengers win and have a party at Avengers Tower where everyone tries to pick up Mjolnir, including Rhodey
Captain America is able to move the hammer just a little bit
Jane Foster (Natalie Portman) and Thor are no longer together and she is dating Chris O’Dowd’s character from THE DARK WORLD.
And apparently there is a new couple within the team:
In the party scene at Avengers Tower, we discover that Banner and Black Widow kinda have a thing for each other. Banner is afraid to consummate anything with her for fear of hulking out and hurting her. He doesn’t trust himself. OUCH! Talk about blue balls, in this case hulk green, hence leading to his “It’s complicated” facebook status update this morning.
The Hulk and Black Widow dating? Id be down to see that. For some reason i got that vibe in the first Avengers movie where Black Widow had to trace Banner. We will see if all these details turn out to be true!
