The film stars Sanjay Dutt, Akshay Kumar, Zayed Khan and Lara Dutta in lead roles, whilst Katrina Kaif stars in a cameo appearance. Kylie Minogue appears in a musical number in the film. Blue released on October 16, 2009, and received negative response from critics. The story & screenplay were written by Anthony D'Souza while the dialogues were written by Mayur Puri. During the time of release, it broke the record for the most expensive Bollywood film ever produced. Loosely based on the Hollywood film Into the Blue (2005), Blue failed to recover its high budget from the box office.
