We got confirmation yesterday of the oft-rumoured ‘Hawkeye’ (played by Jeremy Renner) cameo in next month’s “Thor”. His appearance in the film, or maybe just the clip shown at CinemaCon, is so fleeting though that nobody much got a chance to check out his attire.
Today, at the Disney pal at the Convention, the studio revealed concept art of the character – as he appears in (well, “Thor” but also) 2012′s “The Avengers”.

Superhero Hype jotted down the following summation :

Basically, Hawkeye’s costume is going to be very similar to the Ultimates version of the character. In the concept art, we see Renner wearing similar dark glasses and a leather outfit with a matching over-the-shoulder leather quill for his arrows, only the movie version of Hawkeye has the S.H.I.E.L.D. logo emblazoned on it to show his government allegiances. His precision bow is much like the one used by archers who do it for sports and hunting, which again, is also much like the Ultimates Hawkeye

Latino Review also mentioned it :

Disney/Marvel showed a featurette about the upcoming production of the film. In the featurette, there was an artist rendition of actor’s Jeremy Renner’s Hawkeye character. The costume is not the purple costume from the comic books. But, it is a black sleeveless costume with a little bit of maroon. There is the Hawkeye symbol on the chest and he carries modern professional bow.

Clips of the “Avengers” cast talking about the movie and their parts (Mark Ruffalo apparently confirmed that, contrary to earlier rumours, the Hulk will be a good guy in the flick) were also screened at CinemaCon.

So is this a good thing, that ‘Hawkeye’ is much more like ‘Ultimate Hawkeye’ than the first incarnation of the character?
