Blue is a 2009 Indian Hindi-language action-adventure film co-written and directed by Anthony D'Souza, and produced by Dhilin Mehta under Shree Astavinayak Cine Vision Limited. The film stars Sanjay Dutt, Akshay Kumar, Lara Dutta, Zayed Khan, and Rahul Dev. Katrina Kaif and Kabir Bedi appear in cameo appearances. Loosely based on the Hollywood film Into the Blue (2005) and its sequel Into the Blue 2: The Reef (2009), it explores a diver, haunted by his past, who must confront it in order to save his younger brother and girlfriend from a gangster, while his employer and good friend coaxes him to recover a lost, sunken treasure which he refuses to.

Blue was released during the Diwali festival on 16 October 2009 and received mixed reviews from critics. During the time of release, it was the most expensive Indian film made until then, produced with a budget of more than $21 million. Featuring music composed by A.R. Rahman, Blue failed to recover its high budget from the box office.

Since the launch of Shree Astavinayak Cine Vision Limited in 2003-04, this is the first home production from the company and the first in as many as five years to credit Mehta as a producer by name rather than the company itself; in 2010, the custom was followed up in Dabangg, with Golmaal 3 being the third and last film to do so; it is also the only Ashtavinayak film to be distributed entirely by the company itself without support from other networks.
