Directed by Bedabrata Pain, the viewing is being held in honour of Pain's son Ishaan, who tragically died following an on-set accident during the film's shooting, Mid-Day reports.
Speaking about the incident, a unit member said: "It really broke the director's heart. Shankar, Ehsaan and Loy, the music directors of the film and lyricist Prasoon Joshi were extremely moved by this incident.
"They wanted to pay a tribute to Ishaan and so they composed a special track in his memory.
The song, entitled 'Ishaan', has been recorded by Pain himself and is featured in the film's music album.
"Anurag (Kashyap) and Sunil Bohra have invited the who's who to come and stand together in support of the director," said the source. "SRK has also confirmed his attendance for this special memorial screening, thus pledging his support for the film."
Set in 1930s British occupied India, Chittagong tells the true story of a group of teenage school children who, led by their teacher, instigated the first British military defeat in India.
Anurag Kashyap caused controversy when he suggested that Bedabrata Pain's film is superior to Khelein Hum Jee Jaan Sey, which stars Abhishek Bachchan and also tells the story of the Chittagong uprising.
