, who will be playing Martha Kent in the upcoming Superman: Man of Steel film was a special guest on Wednesday night's The Tonight Show With Jay Leno on NBC, and talked about the secrecy surrounding the up-coming Man of Steel movie.

Expressing her excitement she said, "Oh, I'm not allowed to talk about it. It's top secret. People might hear. I'm playing Martha Kent...Yeah...Yay!! I'm going to be in one of those huge movies. I can't wait to see it already. I'm kind of amazed."

"Of course, there is a lot of secrecy these days, with the Internet and everything, and rumors get started, so I had to read the script under lock and key in a room. You go to the offices, and it's a locked door and the curtains are drawn, and so, that was the time I had."

Also...E! Online interviewed Diane Lane recently and asked her whether she has read the script for the up-coming Superman movie "Man of Steel", in which she'll be playing Martha Kent.

"I read the script under lock and key," Lane told us at the L.A. screening of her new HBO flick, Cinema Verite. "I was locked in a room with the script and was only allowed three hours with it. I nailed it into my memory. I'm really excited. I'm really not allowed to talk much about it, I think, but it does cover the entire range of years, from infancy on." This isn't Lane's first onscreen encounter with the superhero. She starred alongside Ben Affleck in the 2006 docudrama Hollywoodland about the mysterious death of actor George Reeves, star of the 1950s television series Adventures of Superman.

"When I worked on Hollywoodland, I got to experience sort of the behind the scenes of what it was like for the people who were making the television series that I grew up watching, so it's all very inbred in my mind," she said. "But this is going to be a whole reinvention. A visitation and a reinvention."
