Avengers Age of Ultron: New superhero The Vision's look is a mystery even for cast-members

Avengers: Age of Ultron will feature some new heroes, alongside the regular roster, who will help take down the menacing villain Ultron. One of them is The Vision who unfortunately has not been revealed to fans and viewers yet.

Played by Paul Bettany, The Vision is an advancement of Tony Stark's JARVIS and is reportedly designed by Tony and Bruce Banner, in the film.

"Programmed by the combined geniuses of Tony Stark and Bruce Banner and imparted with the ability to fly, project intense energy beams and change the density of his form, the Vision has proved himself a worthy hero, aiding the Avengers in their struggle against the evil A.I. Ultron," teased a leak trading card according to io9.

The makers seem to be keen on keeping the character's look a secret as he's not been revealed in any of the trailers so far.

In fact, it looks like even the cast members haven't seen the complete look of The Vision as yet.

"I haven't seen him," actor Jeremy Renner (Hawkeye) told The Hollywood Reporter. "I kind of keep my head turned away from all of that so I can be surprised when I see the movie. Obviously I saw Paul Bettany in person as the character, but then they do the visual effects and all that sort of stuff. It will be a surprise to everybody in the movie - Ultron as well as Vision, because those characters were so much generated stuff."

Avengers: Age of Ultron is slated for release on 1 May, 2015.
