(BANG) -Nicole Kidman says making the musical movie 'Nine' was like "taking baby steps" back into work.

The 42-year-old Oscar winner - who plays a movie goddess called Claudia Jenssen alongside troubled director Guido Contini, who is played by Daniel Day-Lewis - admits it was difficult going back to work following the birth of her daughter Sunday Rose, who she delivered in July 2008.

Nicole - who is married to country musician Keith Urban - said: "My daughter Sunday Rose was six weeks old when I started work on it? now I have a life! I didn't have one then, but I have one now. I have Sunday Rose and Keith and Connor and Bella."

The actress - who has two adopted children, Isabella, 17 and Connor, 14, from her marriage to Tom Cruise - also revealed a few years ago she was considering walking away from the movie business to "get a life" but that's all changed now.

If she can, Nicole plans to be acting well into old age like her 'Nine' co-star Dame Judi Dench, 74.

She said: "To be someone like Judi Dench - the glorious Judi! She still has that wide-eyed wonder at being an actress."
