A piece of concept art that is believed to have originated with Sideshow Collectibles, which produces licensed Marvel statues, appears to provide by far the best look yet of the character of The Vision, who is being played by Paul Bettany in Joss Whedon’s Avengers: The Age of Ultron, which is due in theaters on May 1st, 2015.  Age of Ultron has wrapped shooting and is now in post-production (see "'Avengers 2' Filming Wraps").

The yellow cape traditionally associated with the character remains as does the overall green tonality of the costume, though it must be said that the colors have been tamped down quite a bit on the brightness scale.  That said, the new image,which appeared on i09, does provide a highly detailed rendering of The Vision in all his android glory, and certainly gives a better look at the character than the murky view provided by the previous Age of Ultron concept posters (see "Marvel Releases the Final 'Age of Ultron' Concept Art Poster").
