Actress Jessica Chastain has called for more education about depression as she paid tribute to her mentor, Robin Williams, at the UK premiere of her new film Salome.
Chastain plays the title role opposite Al Pacino, who also directed the movie along with a simultaneous documentary, Wilde Salome, which tracks its production.
The 37-year-old has become one of the most sought after actresses of her generation following her performance in award-winning film Zero Dark Thirty.
But it was thanks to a scholarship paid for by the late Williams that she was able to keep her place at The Juilliard School in New York where she learnt her trade. Speaking to Sky News on the red carpet in London she said children at middle school and high school should learn about suicide prevention and depression.
"We know that many artists in history have struggled with depression, they have extreme highs and extreme lows but sometimes I wonder if an artist feels free to discuss it openly because so many beautiful things happen you kind of feel like if someone's feeling down there's kind of this stigma of, 'your life is so great, how dare you feel bad about yourself?'
"So I hope that changes because clearly he (Robin Williams) was suffering from depression and didn't feel he could really express that, so I hope we as a society welcome people to talk about depression more."
