There are about a half of dozen superhero flicks currently being promoted in the comic parallel universe, but judging from the reaction to the Avengers: Age of Ultron trailer, all them will be null and void soon enough.
We saw a ton of Avengers: Age of Ultron footage, which starts light-hearted. We see the Avengers sitting around trying to untangle the “whosoever is worthy” thing, regarding who gets to hold Thor’s hammer. And they all think it’s a trick, or a circus sideshow.
Then there’s a ringing sound and they’re all deafened, and Ultron strides into the room, with a crude Avengers logo painted on his slightly misshapen chest. “How could you be worthy? You’re all killers,” Ultron says. “You want to protect the world, but you don’t want to it to change. There’s only one path to peace: your extinction.”
Then a sh*t ton of robots burst through the wall and attack all of the Avengers, plus Maria Hill.
Then there are some hero moments: Captain America enters a place shooting some guns. Stuff is blowing up. Banner staggers to his knees in a snowy forest, looking sickly. Thor uses his hammer to smash a tank. Black Widow is in a medical bay, reaching for some surgical tools. We glimpse Nick Fury looking the way he did at the end of Winter Soldier. And Scarlet Witch is on a bus, approaching some people at the back of the bus with magic in one hand.
If you need further description, look no further in the various reactions found in the gallery.
All indicators point to it being an epic experience for fans and a lucurative one for the studio.
