Tilda Swinton worries constantly about the safety of her children.
The 51-year-old actress raises 14-year-old twins, Honor and Xavier, with her husband John Byrne and admits when she is away she frets about them, creating unlikely situations in her mind of what could happen to them.
In an interview with the New York Post newspaper, she said: "I work at motherhood. Although I travel a lot, I'm never away shooting more than a couple of weeks. I'm very aware I'm responsible for their safety, my imagination works overtime trying to foresee any eventuality. I fire up. The problems expand in my head and take me to dark stuff. My imagination takes on all disasters."
Tilda - who lives in Scotland with her family and also her live-in lover Sandro Kopp - admits her role in her latest film 'We Need to Talk About Kevin' resonated with her as a mother because of the emotionally challenging subject matter.
In the movie, the British actress plays mother Eva Khatchadourian who struggles to bond with her son, who then goes on to massacre students and teachers at his school, and she insists the fear of not developing a maternal bond is something all women can relate to.
She explained: "The movie's a phantasmagoria. About a woman's mind. Not a social commentary. The prize-winning book had a big impact in London. A worst-case scenario nightmare of raising a child with mother and son at dagger's points. Having a baby half-heartedly, hoping glue kicks in and has its stamp. The baby she's caring for at arm's length never stops screaming . Mothers in the audience align. They recognize the danger. You can see the desperation."
