Valentine's Day is celebrated every year on Feb 14 and the film is also coming out on the same day.
Featuring Priyanka Chopra, Ranveer Singh, Arjun Kapoor and Irrfan, "Gunday" made on an approximate budget of Rs.50 crore which includes promotions, will reportedly hit more than 2,000 screens across the country.
Trade analyst Rajesh Thadani is hopeful about the action thriller's box office prospects.
"The film will have a bumper opening. It might even cross Rs.100 crore," Thadani of Multimedia Combines told IANS.
Produced under the prestigious banner of Yash Raj Films (YRF), "Gunday" holds a lot of significance for its makers as it was the last narration that the late Yash Chopra, who started YRF, heard.
"It's a very special film for us because this was the last script that Yash Chopra heard. It's special for us to do the film because he really loved the script and he believed in it," Zafar had said earlier.
Set in the 1970s West Bengal, the film tells the story of two friends - Bala and Bikram - played by Arjun and Ranveer respectively.
The two grow from being small time inconsequential coal thieves to the most powerful black marketing mafiamen.
If the story is atypical, the actors also sport different avatars in the film. In fact, Ranveer and Arjun went many shades darker for the movie.
The plot fits well with the time it portrays and also includes the world of cabaret dancers with Priyanka playing cabaret dancer Nandita.
To look convincing on screen, the actress trained with French cabaret dancers for the song 'Asalaam e ishqum'.
Parts of the film have been shot in Kolkata and Durgapur in West Bengal. The makers also canned a song in Oman.
Arjun and Ranveer will be seen together for the first in "Gunday" and viewers would like to see their on screen chemistry after their crackling off screen bonding.
