Adaptations from comics to film pretty much guarantee major changes, but looks like Vision is gonna be Vision, basically.
Age of Ultron has got a lot riding on it. Marvel's Avengers has created a nice bump for all the Marvel movies that have come out since. And now the Avengers sequel has to do all that again, but be bigger and better than what came before. That's a sequel's job.
And so Ultron is being brought in, but sans Hank Pym. Which is a bummer of a change. But Hank didn't make Vision in the comics -- Ultron did. And, in that spirit, it seems Age of Ultron will feature a similar story.
According to a recent report in Entertainment Weekly, Vision will be created "by Ultron to show he has the power to create life too. (Did we mention Ultron has major daddy issues?) The Vision will be portrayed by Paul Bettany, who has already been a part of the Marvel movie universe as J.A.R.V.I.S., the Siri-like artificial intelligence who serves as Tony Stark’s laboratory sidekick."
So the root of that origin is pretty similar. But there's also the choice of Paul Bettany, who previously voiced J.A.R.V.I.S., in the part. Will that play into the origin in an important way? Well, according to Joss Whedon himself, "“It’s not coincidence."
So there you are: Vision's origins -- revealed. Well, part of them, anyway.
What do you think?
