Nicole Kidman feared she would 'let down' real-life adoptive mother Sue Brierley, who she played in 'Lion'.
The 49-year-old actress - who has more than 30 years experience in the film industry - felt the pressure to get things right on the set of the Oscar-nominated movie.
When asked whether she felt cautious over meeting the adoptive mother Sue Brierley, she told Total Film magazine 'It was more like I didn't want to let her down. Obviously, it's a supporting role, so it's not her story - and she contributes to it. But her story itself - her life story - is so compelling.'
The film is based on a five-year-old Indian boy Saroo, played by Sunny Pawar and Dev Patel, who gets lost on the streets of Calcutta, thousands of miles from home. He is eventually adopted by a couple in Australia and 25 years later, he sets on a mission to find his lost family.
Kidman admitted she was worried she wouldn't be able to do Sue's story justice and 'honour' her life.
She added 'I was like, "Gosh, I hope I can somehow get her essence into the amount of screen time I have so you can really feel who she is and what she is." So I wasn't reticent to meet her, but I didn't want her to feel that everything she shared with me - because I spent so much time with her - was not on the screen, because it couldn't be. But I wanted to somehow honour her life.'
And Kidman says that when she first read the script, she wasn't aware that it was based on a real-life story but still found it hugely emotional to play.
