“Avengers: Age of Ultron” is shaping up to be one of the biggest movies of 2015. Fans have been treated to a whole mess of teases for the upcoming sequel, but, one of the biggest mysteries seems to be the newest/oldest addition to the team, Paul Bettany’s “The Vision.”

In a recent interview from the set of the movie, writer and director Joss Whedon opened up about the look of the third superhero which will be joining the iconic team of Marvel characters when the “Avengers” sequel premieres next year.

“We make them as close as we can. The stunt guy -- we make allowances for the shape of his face and padding and things that we’re putting on him. But they’re not meant to look different,” he told reporters via IGN. “One of the guys draws something unbelievably beautiful, and we try to create that in real life, and it takes a long time. The first tests were very Violet Baeuregarde. It really took a long time to get to a place where we felt like - even though we will work on him in post- that he walks on, and we go, 'Oh, it’s the Vision - my God.'”

Whedon also confirmed how the film will tackle the character’s origin story. Ultron will create Vision similar to the way he was made, from an artificial intelligence program created by Tony Stark/Iron Man (Robert Downey Jr.). This isn’t exactly surprising as Paul Bettany’s casting basically confirmed the story months ago. Surprisingly, Bettany has been in the Marvel Cinematic Universe longer than most of the cast. He’s voiced Ironman’s digital assistant J.A.R.V.I.S. since the first movie.

Although a lot is known about the character and his origin, Vision’s look is still shrouded in mystery. So far, the only idea of what he will look like that can be considered canon is a distant drawing of the character. The drawing was released piece-by-piece at the 2014 San Diego Comic Con and features the whole team, including Scarlett Witch (Elizabeth Olsen) and Quicksilver (Aaron Taylor-Johnson), battling a horde of Ultron robots. In the distance, the Vision can be seen in his yellow cape floating above the fray.

Given Whedon’s most recent comments, and the fact that the character has not been featured in either of the film’s trailers, it’s looking like Marvel is holding the first look at the Vision for some kind of special reveal. It’s possible fans will have to pay the full ticket price before getting a look at Bettany in character. 

"Avengers: Age of Ultron" premieres May 1, 2015.
