Marvel releases new teaser for ‘Avengers: Age Of Ultron’ – watch

Joss Whedon's superhero sequel is set to open in cinemas on May 1

Marvel has released a new TV spot teaser for Avengers: Age Of Ultron.

Avengers: Age of Ultron is the sequel to 2012’s The Avengers, which raked in over $1.5 billion (£1 billion) at the box office worldwide to become the third highest-grossing film of all time. Joss Whedon returned to serve as writer-director on the sequel, which is set to open in cinemas on May 1.

Robert Downey Jr (Iron Man), Scarlett Johansson (Black Widow), Chris Evans (Captain America), Chris Hemsworth (Thor) and Mark Ruffalo (Hulk) all reprise their roles from The Avengers, joined by newcomers Paul Bettany (the vision), Aaron Taylor-Johnson (Quicksilver) and Elizabeth Olsen (the Scarlet Witch). Former Boston Legal star James Spader provides the voice of the villainous Ultron.

Marvel’s official plot synopsis for the sequel teases: “With S.H.I.E.L.D. destroyed and the Avengers needing a hiatus from stopping threats, Tony Stark attempts to jumpstart a dormant peacekeeping program with Ultron, a self-aware, self-teaching, artificial intelligence.

“However, his plan backfires when Ultron decides that humans are the main enemy and sets out to eradicate them from Earth, and it is up to Iron Man, Captain America, Thor, the Hulk, Black Widow and Hawkeye, along with support from Nick Fury and Maria Hill, to stop him from enacting his plans. Along the way, the Avengers encounter the powerful twins, Pietro and Wanda Maximoff, as well as the familiar Vision.”
