Is this true? No official word has come out as of yet. Right now it is a fun rumor, with Flawed Hollywood noting "The Avengers just happens to be getting made into a movie in 2011, around the time that Desperate Housewives will be ending."
The Los Angeles Times speculates that the actress is up for the role of Janet Van Dyne, better known as The Wasp. The Avengers is set to hit theaters sometime in 2011, so that gives us plenty of time to air this rumor out.
Marvel's The Avengers was released May 4th, 2012 and stars Robert Downey Jr., Chris Evans, Mark Ruffalo, Chris Hemsworth, Scarlett Johansson, Jeremy Renner, Tom Hiddleston, Clark Gregg. The film is directed by Joss Whedon.
