The Los Angeles Times‘ Hero Complex blog broke the news that Snyder had telephoned the actress personally to offer her the part earlier on Sunday.
In an interview with the blog, Snyder described the role of Lois Lane to be a “lynchpin” to the movie he is planning.
It goes back to what I’ve said about Superman and making him really understandable for today. What’s important to us is making him relevant and real and making him empathetic to today’s audience so that we understand the decisions he makes. That applies to Lois as well. She has to be in the same universe as him [in tone and substance].
As Snyder has ramped up casting for his Superman film, a number of actresses have been mentioned as being under consideration for the role including Dianna Agron, Malin Akerman, Kristen Bell, Jessica Biel, Rachel McAdams, Kristen Stewart, Olivia Wilde and Mary Elizabeth Winstead.
Adams will be joining a cast which features Henry Cavill as Clark Kent/Superman with Kevin Costner and Diane Lane as his adoptive parents Jonathan and Martha Kent.
