A possible new recruit for the second Avengers movie may be "Ms. Marvel". She is a super hero that was a former employee of the United States Air Force with super powers that make her resistant to toxins and poisons as well as a body that is virtually invulnerable and indestructible.
Reports in the UK's Daily Mail claim that director Joss Whedon may be looking at either Ruth Wilson (The Lone Ranger, Saving Mr Banks) or Emily Blunt (The Adjustment Bureau, Looper) to play the role. It also claimed that "The Avengers 2" is due to start filming next year.
With a 2015 release date scheduled, this is most probably going to be one of many rumored stories that will be hovering around this movie. Time will only tell how many actually turn out to be fact.
