This was quickly followed by Joss Whedon's announcement that The Avengers 2 was going to officially be titled The Avengers: Age of Ultron.
Fans began to speculate that Vin Diesel is going to play Vision, an android created by Ultron. But no one has really put two and two together, that Ultron may very well be personified by the actor instead.
Why do we think so? One, which people in the know are quick to point out, is that Vin Diesel is wrong for the part of Vision. But more importantly, Joss Whedon has been pretty straight with fans, and he's gone on record stating Quicksilver and Scarlet Witch are the only two main new additions to the Avengers team. Its very unlikely that we'll see Vision in The Avengers: Age of Ultron, as the earth-destroying android is also getting a brand new origin story.
Watch this video, and tell us Vin Diesel wouldn't sound pitch perfect as this sentient robot out to kill the Avengers team.
What do you think? Is Vin Diesel the voice of Ultron? Will he play the character as motion capture? Or is Marvel going to paint him Vision green and let him lay sloppy kisses on the much younger Saoirse Ronan as Scarlet Witch?
Avengers: Age of Ultron comes to theaters May 1st, 2015 and stars Aaron Taylor-Johnson, Scarlett Johansson, Robert Downey Jr., Elizabeth Olsen, Chris Hemsworth, Chris Evans, Cobie Smulders, Jeremy Renner. The film is directed by Joss Whedon.
