According to ComicBook.com on Dec. 8, in an interview with Amy Adams for her current movie "American Hustle", she was asked if she'd be interested in partaking in a love triangle in Zack Snyder's "Batman vs. Superman" film. She actually would prefer it if she'd be in a film where they'd get along and work together instead of being adversarial. Adams feels it would be better to not have females always partaking in any kind of cat fights. Of course, Selina Kyle's Catwoman might beg to differ.
Adams was also caught unaware of the fact Wonder Woman was even revealed as being in the Zack Snyder sequel and that Gal Gadot would be the one to take on the mantle of the Amazonian.
There will also later be an extended version of the Amy Adams interview entailing more content.
The new Superman is played by Henry Cavill and will be appearing along with Ben Affleck in Zack Snyder's "Batman vs. Superman".
