I've not heard of this blog before, not sure if it has "sources" or if it's just a well run fan blog. A guy somewhere else is always linking to it and cites he does get some good scoops.
So, salt shaker in hand here is the rumor
I'm passing along to the mill.
There is talk that Hayley Atwell could end up taking on the role of Sharon Carter in Captain America: The Winter Soldier. If this is the case, where does this leave Anna Kendrick's role in the film? Anna has been a front-runner for an unnamed new female part. I wouldn't be shocked if this turns out to be Jessica Drew (Spider-Woman) and not Sharon Carter.
I mentioned to the guy who posted this that he never claims to have information. It just sounds like the site runners own wish to happen.
Still Kendrick as Spider-Woman sounds nice plus she's about the best real talent acting wise to come out of the Twilight
