Amy Adams Joins Growing List of 'Superman' Cast

Amy Adams is the newest actress to join the Warner Bros' reboot of Superman, to be directed by Zack Snyder. See all the stars lined up to star in the film -- set for a December 2012 release -- so far:

1. Superman - Henry Cavill
The British actor, best known for his work on Showtime's period drama The Tudors, was in the top three or four contenders since Day 1, an insider tells The Hollywood Reporter. Cavill's closest competitor was Matthew Goode, another British actor who was one of the stars of Snyder and Warners Bros.' Watchmen comic book movie.

2. Lois Lane - Amy Adams
Snyder calls her "one of the most versatile and respected actresses in films today. Amy has the talent to capture all of the qualities we love about Lois: smart, tough, funny, warm, ambitious and, of course, beautiful." Phyllis Coates, Margot Kidder and Kate Bosworth have played the role before her.

3. Superman's Mom - Diane Lane
Lane plays Martha Kent. Says Snyder, "This was a very important piece of casting for me because Martha Kent is the woman whose values helped shape the man we know as Superman. We are thrilled to have Diane in the role because she can convey the wisdom and the wonder of a woman whose son has powers beyond her imagination."

4. Superman's Adoptive Father - Kevin Costner
The part of Pa Kent was famously played by Glenn Ford in the Richard Donner Superman movie; the character suffered a heart attack, lending the movie some of its poignancy. Snyder says: "Jonathan Kent is the only father figure Clark has ever had, the man who was there to help Clark understand what he was meant to do in the world as Superman. Kevin will be able to communicate the quiet strength of this rural American man who raised the greatest superhero of all time."
