Scarlet Witch
Even though 'The Avengers: Age of Ultron' won't hit screens until 2015, the casting process is under way and Joss Whedon is looking for his Wanda Maximoff -- also known as The Scarlet Witch -- for the upcoming movie. Previously Saoirse Ronan was the top contender, but it appears she's passed and that the part may have been offered to Elizabeth Olsen.
