Walking the red carpet ahead of the world premiere of The Sky is Pink at the Toronto International Film Festival on Friday, actress Priyanka Chopra Jonas was a stunner in black and white frill gown. She walked the red carpet with Farhan Akhtar and his girlfriend Shibani Dandekar, Rohit Saraf and the film’s director, Shonali Bose.

“It was a really hard juxtaposition of real life for me,” Chopra said, “Especially because I was getting married and at the same time this film deals with loss, loss of a child, which is such an unnatural way of being.”She added that, although the experience “was very trying,” the support of husband, Nick Jonas, whom she married in December, helped.

The Hindi-language film tells the true story of the Chaudhury family, narrated by their deceased teenaged daughter, Aisha, played by Zaira Wasim. It chronicles the practical, emotional and relationship struggles faced by Aisha’s parents Aditi and Niren, portrayed by Priyanka and Farhan Akthar, as she fights, and ultimately succumbs to, a rare genetic terminal illness that took her older sister’s life decades earlier.

The real-life Aisha Chaudhury died on Jan. 24, 2015, at 18, the day after her book, My Little Epiphanies, was published. The Sky is Pink ends with photographs and video clips of the real Chaudhury family living the moments depicted in the film, including a TEDx talk Aisha gave in India in 2014.

“You have to be very strong as partners to go through what they went through,” Farhan said on the red carpet. He added he tried to “approach this part with a lot of respect, and make sure that the dignity and grace that they’ve shown in real life comes through in the performance in the film.”
