Go behind the scenes of Avengers: Age of Ultron

With anticipation for Avengers: Age of Ultron reaching fever pitch, here's a new video exploring the increasingly complex role of Tony Stark/Iron Man (Robert Downey Jr.) in the Marvel Cinematic Universe.

As you may know, Stark is responsible for endangering the world in the latest superhero adventure, as his peacekeeping 'Ultron' plan backfires. Stark's experiment results in the birth of a rogue A.I. (voiced by James Spader), who harbours plans to turn the Avengers against one another.

Interestingly, as the featurette explains, Ultron also bears characteristics of his own creator. Yes, not only do we have a baddie planning to destroy the world – he's also neurotic and temperamental. Is there anything worse?

Take a look at the video in which Downey Jr., co-star Chris Evans, writer/director Joss Whedon and Marvel chairman Kevin Feige prep us on what to expect from the Ultron character.
