The National Award-winning actress essays the lead role along with actor Farhan Akhtar. Her Purple Pebble Pictures is co-producing the film.
"'The Sky Is Pink' is a story that I connected with from the minute I heard it and in Shonali's hands, it's been crafted into a moving, beautiful film that will renew our faith in love and life.
"It's what led me to not only take on the challenging role of Aditi Chaudhary but also to co-produce it. I am so proud of this film and am honoured that the film's world premiere will take place at the Gala Presentation at TIFF 2019.
"I'm looking forward to being back at TIFF once again to showcase our a small package of love to the world," said Priyanka, whose production "Pahuna: The Little Visitors" was also screened at the fest two years ago.
"The Sky Is Pink" is a love story of a couple - Aditi and Niren Chaudhary - spanning 25 years, told through the lens of their spunky teenage daughter - Aisha Chaudhary, who was diagnosed with a terminal illness.
For Bose, "The Sky Is Pink" is a deeply personal and an incredibly special film. "At its core, this is an extraordinary story of what it means to be a family. I am honoured that the film will premiere at TIFF," she added.
"The Sky Is Pink", also starring Zaira Wasim, is produced by RSVP and Roy Kapur Films, in association with Ivanhoe Pictures and Purple Pebble Pictures.
