As you all know by now Jeremy Renner is set to play Hawkeye in Joss Wehdon's The Avengers. At one point Renner said that the character would pop up in the film Thor saying, "If I was a betting man, I would bet that Hawkeye would probably show up in Thor, and then be in The Avengers. But do I know for sure? I can’t say. But I’d love for that to happen. It’d be fun." Not long after he said that he said that he would not appear in Thor, claiming that it "was just one of those things that got blown way out of proportion," but now The Wrap say's that he will have a cameo in Thor.
There seems to be a lot of confusion over a little cameo role. Here's is the intel the site received,
An individual who has seen an early cut of Thor confirmed to TheWrap that Renner's Hawkeye appears in the film, although the person declined to elaborate on the context of the character's appearance or when it will occur. They did, however, confirm Jackson's earlier statements that Nick Fury does not appear in Thor.
There is still no official confirmation of this, only a guy claiming to have seen the movie and saw the character. I'm sure we'll see our fair share of easter eggs and cameos in Thor, and this could very will be one of them, only time will tell.
