The movie will open with Captain America, Nick Fury, Black Widow and Falcon defeating Baron Strucker and rescuing Quicksilver and Scarlet Witch, at which point Fury will ask them to join the Avengers and they'll accept.
would Baron Strucker get away from them (considering that he is supposed to have a kind of big part), or would they just defeat him?
and also is Falcon officaly in Avengers?
No, he isn't. I made that mistake because Falcon was added to the imdb page for "Age of Ultron", but apparently imdb screwed up.
Sorry about that.
but it is rumored that Baron Strucker wll be in Avengers 3. i guess its too early to tell. :(
I said they are gonna defeat him, not kill him. All it means is that they are gonna knock him out so they can rescue Quicksilver and Scarlet Witch. Then Quicksilver and Scarlet Witch join the Avengers, and they all fight Ultron.
Baron Strucker can still come back in "Avengers 3" or "Captain America 3" or even in a Black Widow solo movie.
What I mean to say is that these movies are now gonna follow the X-Men mold, with the main characters putting aside their differences to defeat a common enemy.
Even if Scarlet Witch and Quicksilver are "bad", Ultron represents a threat to their lives, which means they are gonna team up' with the X-Men to defeat them.
