Ultron vs Hulk in Avengers 2 teaser
A new trailer for The Avengers: Age Of Ultron has been unveiled, which shows Ultron going head to head with the Incredible Hulk.
The 90-second clip for Marvel's upcoming superhero sequel features the Avengers team reuniting to save the world from supervillain Ultron, played by The Blacklist's James Spader.
The sneak peek begins with hordes of people evacuating, with Chris Evans' Captain America alter-ego saying: "This vulnerable earth needs something more powerful than us."
Robert Downey Jr, who will reprise his role as Tony Stark/Iron Man, then says: "Everyone creates the thing they dread..." hinting to the villainous robot.
There are glimpses of Mark Ruffalo's Hulk, Jeremy Renner's Hawkeye, Scarlett Johansson's Black Widow and Chris Hemsworth's Thor, as well as Samuel L Jackson, who is back as S.H.I.E.L.D. leader Nick Fury.
Aaron Taylor-Johnson's alter-ego, Quicksilver/Pietro Maximoff, and Elizabeth Olsen, as his screen sister Wanda/Scarlet Witch, are also seen.
Joss Whedon's follow-up to 2012's Avengers Assemble will be released in UK cinemas on April 24.
