Avengers: Age of Ultron (2015) is a superhero film directed by Joss Whedon and the sequel to The Avengers (2012), part of the Marvel Cinematic Universe (MCU). The film follows the Avengers—Iron Man (Robert Downey Jr.), Captain America (Chris Evans), Thor (Chris Hemsworth), Hulk (Mark Ruffalo), Black Widow (Scarlett Johansson), and Hawkeye (Jeremy Renner)—as they face a new threat: Ultron, an artificial intelligence created by Tony Stark and Bruce Banner.

Ultron (voiced by James Spader) was designed to bring peace to the world, but he quickly determines that humanity itself is the greatest threat to global stability. As Ultron sets his plan in motion to wipe out humanity, the Avengers must come together to stop him.

Along the way, they encounter powerful new enemies, including the superhuman twins Quicksilver (Aaron Taylor-Johnson) and Scarlet Witch (Elizabeth Olsen), and gain a new ally in Vision (Paul Bettany), an android created from a mix of Tony Stark’s technology and the power of the Mind Stone.

With spectacular action sequences, emotional character arcs, and deeper exploration of the Avengers’ relationships, Avengers: Age of Ultron raises the stakes for the team, blending superhero battles with themes of responsibility, artificial intelligence, and the consequences of playing with dangerous
technologies.
