Latino Review says:
Earlier today we posted that Diane Lane briefly spoke with E! Online stating that she has in fact read the script for the new Superman movie titled "Man of Steel," which Zack Snyder is directing and Christopher Nolan producing.
Lane of course is playing Martha Kent, the adoptive mother of the titled hero played by Henry Cavill.
She gave hints at the film's structure by saying:
"It does cover the entire range of years, from infancy on."
