Nicole Kidman: ‘I still act like I’m 21’

Oscar winner Nicole Kidman has said that she still acts like she's 21 when it comes to acting roles.

The star told a Cannes press conference she likes to make "bold" choices, as if she were at the start of her career, BBC News reports.

Kidman said while she doesn't have to work, she does so because of her passion for cinema.

The star of The Killing of the Sacred Deer, in competition at Cannes, said her young children will be banned from seeing the dark psychological thriller.

Kidman has two grown-up children from her marriage to Tom Cruise and two younger daughters with her current husband singer Keith Urban.

"My (younger) children have very little understanding of what me or my husband do. Their lives are obviously far more important!"

She added: "I'm at that stage in my life where I still try to act as if I'm 21 and starting my career.

"At this stage of my life, I'm just trying to stay very bold and open and try things and support film-makers I believe in."

The Killing of the Sacred Deer features an eminent surgeon Steven Murphy - played by Colin Farrell - who adopts a teenager into his family. Things start to go horribly wrong when the boy turns against Murphy.
