Apparently today is the day that Marvel rumors get confirmed.  We just heard that Bradley Cooper is in early talks to voice Rocket Raccoon in Guardians of the Galaxy, and now THR has confirmed that Elizabeth Olsen is in final negotiations to portray Scarlet Witch in Joss Whedon’s sequel The Avengers: Age of Ultron.  We previously heard that Saoirse Ronan was eyed for the Scarlet Witch role, but when she apparently passed, Marvel moved on to Olsen.  Now it appears that the Martha Marcy May Marlene actress’ deal is nearly done, and she will in all likelihood be playing Scarlet Witch opposite Aaron Taylor-Johnson as brother Quicksilver in the Avengers follow-up.  Hit the jump for more.

Kick-Ass 2 star Aaron Taylor-Johnson’s deal isn’t yet closed, but he’s been talking pretty openly about joining the Marvel universe as of late.  He and Olsen just finished working together on Warner Bros.’ Godzilla, so should they team up in Age of Ultron they will already have a rapport.  Scarlet Witch and Quicksilver are presumed to be the two biggest additions to the Avengers team in the sequel, which will find the heroes fending off the angry robot Ultron.  Scarlet Witch, interestingly enough, will bring more magic into the equation for the Marvel superheroes, as her powers include the ability to affect certain outcomes by altering probabilities.

Olsen will be seen later this year in the Beat poet drama Kill Your Darlings and as the female lead in Spike Lee’s Oldboy opposite Josh Brolin.  Filming on Avengers 2 will begin the first week of March in anticipation of a May 1, 2015 release date.
