After weeks of rumors, Elizabeth Olsen was recently confirmed to play Scarlet Witch in 'The Avengers 2' (officially titled 'The Avengers: Age of Ultron'), but the actress only just acknowledged the apparently secret casting. Now she's letting some more details fly about this mysterious new addition to the Marvel movie universe, so what can we expect from Scarlet Witch on the big screen?

In an interview with Ain't It Cool News while promoting her upcoming film 'Oldboy,' Olsen spoke a bit about 'The Avengers 2' and her role in the film as Scarlet Witch. She'll be reuniting with her 'Oldboy' co-star Samuel L. Jackson, who reprises the role of Nick Fury in the 'Avengers' sequel, and her 'Godzilla' buddy Aaron Taylor-Johnson, playing her onscreen brother Quicksilver.

Olsen wasn't quite familiar with Scarlet Witch before she got the part, but she's been doing a lot of studying by reading the comics since then, and spoke a bit about some of the powers her character has:

She's crazy. She has more things wrong with her than any character I've ever played. She can tell you where an object has been, she can tell you what your future is, she can connect with the dead and people from the past, the future, other universes, and she's the only person in this universe who's capable of doing that. She's unbelieveable; it's so cool. I grew up loving 'Star Wars' and 'Lord of the Rings,' and anything that has another type of world or universe aspect to it is so fun.

The actress also stated she has a sense of what she'll be wearing in terms of her superhero costume in the film, but she has "logic and mind enough not to share it."

Olsen starts shooting 'The Avengers 2' in the spring, joining a cast that includes returning actors Chris Evans, Scarlett Johansson, Robert Downey Jr., Mark Ruffalo and Chris Hemsworth, as well as James Spader voicing the villainous Ultron. The film hits theaters on May 1, 2015.
