Nicole Kidman isn't "proud" of her performance in Australia.

The 41-year-old actress has revealed she "squirmed" in her seat throughout the Sydney premiere because she was so uncomfortable watching herself on screen.

She said: "I can't look at this movie and be proud of what I've done. I sat there, and I looked at Keith and went, 'Am I any good in this movie?' But I thought Brandon Walters and Hugh Jackman were wonderful. It's just impossible for me to connect to it emotionally at all."

Nicole was so nervous about her performance she fled Australia as soon as the premiere was over with husband Keith Urban and their 5-month-old daughter Sunday Rose.

She said: "We ran because I didn't want to read anything. I didn't want to know. I saw my sister and my family and we saw Keith's family and then we were straight on a plane."

Nicole added she only attended the premiere to please the film's director Baz Luhrmann.

She said: "I don't usually see my films, but because of Baz I had to see it. I saw Moulin Rouge. I've really only seen that and this in my whole career. It gets worse as I get older."
