Ultron reigns supreme in final trailer for Avengers: Age Of Ultron: watch now

Following a call to fans from Marvel - urging them to retweet using the hashtag #AvengersAssemble - the new Avengers: Age Of Ultron trailer has been unlocked online.

Check out the phenomenal new trailer, below...

A boisterous third trailer, it simmers quietly for its opening few seconds until the big bad dishes out a killer one-liner. “People look up to the sky and see hope,” drawls the evil Ultron. “I’ll take that from them first.” Cue a series of dazzling action shots interspersed with brand new footage.

The most notable sequences include: an extended glimpse of Ultron’s underlings scrabbling over debris, Bruce Banner and Black Widow veering dangerously close to smooch territory and a handful of Avenger-specific action scenes.

Some of the coolest moments are when two franchise newbies are under the spotlight; Scarlet Witch (Elizabeth Olsen) works her mojo on Black Widow while her brother Quicksilver (Aaron Taylor-Johnson) delivers the pain to Cap.

Saving the juiciest for last, we finally see Paul Bettany as Ultron’s twisted creation, Vision, right when he opens his eyes.

Starring Robert Downey Jr., Chris Hemsworth, Chris Evans, Scarlett Johansson, Mark Ruffalo and Samuel L. Jackson, Avengers: Age Of Ultron opens in the UK on April 23, and in the US on May 1.
