I would say Kudos to director Milan Luthria who made such an intense film with so much finesse. Once Upon A Time In Mumbai has evolved as a new way of representing Mafia gangs. There are numerous WoW factors in the movie such as excellent script, power-packed dialogue delivery, bold one-liners, slapstick humor, breathing life into character performances and amazing background score. Music given by Pritam is like icing on the cake. Nothing was out of place; Total Paisa Wasool; Complete Entertainer Been long since your eyes saw some good cinema, its time to give them a treat!!!
