Rachel Weisz On Motherhood, New Film

(CBS)  Rachel Weisz will remember 2006 for a long time: back in March, she won the Academy Award for best supporting actress for "The Constant Gardener." Two months later she gave birth to her first child.

As Harry Smith reports, she's now back on the big screen, starring in "The Fountain."

"I was fortunate enough to see you on Academy Award night, there you are so pregnant, holding your trophy and I kept thinking what was that night like for you? Because you were great with child, right?" Smith asks.

"That's one of my favorite expressions in the world 'great with child.' It's biblical," says Weisz, laughing. "It's wonderful. I was seven months exactly. I was kind of like a beached whale, waddling around."

Asked what it was like to be waiting with all the anticipation on Oscar night, Weisz says, "Yeah, I mean, your hormones are running crazy, you need to run to the restroom a lot when you are pregnant, so I was running out at the commercial breaks. In the best of times, I have never even been to the Academy Awards, so just to even go to that and see the scope of that – you have been there and seen it – it's overwhelming."

Her son, named Henry, is now five and a half months.

"What is that like to be young and successful and brilliant and have a little boy?" Smith asks.

"Well, I mean, I have fallen deeply in love. I am love with a little boy called Henry. Yeah, I mean, I'm a working mom now, so I have joined the club of all the millions of other women on the planet who are working moms and I take my hat off to them. It's a balancing act," she says.

Weisz' latest project, "The Fountain," is a film conceived by her partner, Darren Aronofsky.

It's a love story that really travels over a millennium: in one phase, she plays the Queen of Spain, in another, a young woman who is dying. Her love interest in the film is portrayed by Hugh Jackman.

"Yeah, there's a lot of love and passion. I think it's very romantic, a romantic film. It's for anyone who believes in love who has been in love," she says.

Asked if she believes in true love, Weisz says, "Yeah, I mean I think relationships take work. I do. But I am a sucker for stories about lovers, you know, lovers who are destined to be together, lovers that can transcend time, like these . Their love lives on eternally. I don't know if real life feels exactly like that and I am very in love but it never feels quite like in the movies."

During the making of the film, Weisz actually lived separetly from her partner. "There were three months we were working together and we wanted to create a professional relationship. These movies are an intense love story between myself and Hugh Jackman, so just to create boundaries," Weisz explains.
