Soni Razdan, Mrunal Thakur, and Priyanshu Painyuli join the cast of Ishaan Khatter's upcoming war film, Pippa.

Directed by Airlift filmmaker Raja Krishna Menon, Pippa features Ishaan as Brigadier Balram Singh. Mrunal and Priyanshu are roped in to play the roles of Ishaan's siblings, while Soni Razdan will play their mother.

"With Mrunal and Priyanshu joining Ishaan, we have three of the most exciting young actors coming together. Personally, I'm very excited to work with such extraordinary young talent and look forward to the energy they bring to Pippa," said the director.

Brigadier Balram Singh Mehta of the 45th Cavalry tank squadron, along with his siblings, fought on the eastern front during the Indo-Pakistan war of 1971, and the film recounts his story. It is based on his book, The Burning Chaffees.

The film's title highlights the Russian war tank PT-76, popularly known as Pippa. The project portrays the coming-of-age of a young Mehta as well as of India. It is co-produced by Ronnie Screwvala and Siddharth Roy Kapur.

"We were looking for great actors who would complement each other to create a believable family unit, and with Mrunal, Priyanshu, and Soni Razdan on board to join Ishaan, I am happy that we have more than achieved what we set out to do with the casting," Roy Kapur said.

Screwvala added, "Pippa is a story that chronicles an Indian victory in 1971 through the eyes of the Mehta family and signing on fine actors to essay the members of this brave family was our foremost priority. I'm glad we have talented actors like Mrunal and Priyanshu on board, who along with Ishaan will spearhead this story of triumph that needs to be told."

Pippa is slated to hit theatres late next year.
