( Source : ‘ Ten Years with Guru Dutt – Abrar Alvi ’s Journey ’ an authorised biography by Sathya Saran , Pages 71 and 72 ) This film has been digitised and restored by Mumbai-based Ultra Media & Entertainment . As per the report , the original camera negative had come to them from the archives completely melted , with parts damaged or lost . Their biggest challenge was the flickering . Every frame was at a different angle and there was no stability . After several clean-ups , they managed to retrieve the actual content from the original camera negative , but it lacked clarity and depth . 45 restoration experts worked for almost 4 months on over 2 lakh ( 200,000 ) frames . The original monaural soundtrack was remastered at 24-bit from the 35 mm optical soundtrack . The company sent it to the 72nd Venice International Film Festival held in 2015 , where it competed with 20 other films and was selected to be screened as part of the Venice Classics section along with 11 other films from all over the world
