The completed movie title is Avengers: Age of Ultron.
Released in 2015, the film is the sequel to 2012’s The Avengers and the 11th movie in the Marvel Cinematic Universe. Joss Whedon wrote and directed it, while Marvel Studios produced it for distribution by Walt Disney Studios.
Ultron is an artificial intelligence created when Tony Stark and Bruce Banner attempt to build a global defense system. Instead of protecting humanity, Ultron concludes that peace requires humanity’s destruction. The character is voiced by James Spader and serves as the film’s main antagonist.
A common mix-up is confusing the movie with Age of Ultron, the title of a 2013 Marvel Comics storyline. The MCU film borrows the name but is not a direct adaptation of that comic. Avengers: Age of Ultron introduced Wanda and Pietro Maximoff to the MCU and was followed by Avengers: Infinity War and Avengers: Endgame.
