Speculation that JARVIS, the artificial intelligence created by Tony Stark, would become Vision has essentially been confirmed by the casting of Paul Bettany. Vision will debut in The Avengers: Age of Ultron and Bettany has been the voice of JARVIS in the three Iron Man films.
The timing for the character also makes sense in that he been attached romantically to Scarlet Witch in the comics, who also will appear for the first time in the team-up sequel. Ultron is also expected to have been created by Stark and Vision could fit into the plot in any number of ways considering the numerous versions of him from the comics over the years.
The Avengers: Age of Ultron will release on May 1, 2015. It follows two more Marvel films in 2014 – Captain America: The Winter Solider on April 4 and Guardians of the Galaxy on August 1.
