The underworld drama with the retro appeal is ruling the hearts of cinegoers worldwide and the movie is roaring at the Box Office.

The Ajay Devgn and Emraan Hashmi-starrer is getting appreciated for its dialogues and marvellous acting along with Preetam’s fine music.

The movie had the biggest opening overseas ever, especially in Dubai, for any Ajay Devgn or Emraan Hashmi starrer.

Trade sources claim the movie has grossed over Rs.30 crore (Rs.300 million) in the domestic market in its initial run and is expected to touch the Rs.75 crore gross mark in its overall run worldwide. In the Middle-East, 'Once Upon...' grossed around AED 1 million (close to Rs.13 million) in Dubai in four days (as movies release on Thursdays there).

Co-produced by Balaji Telefilms and Popcorn Entertainment the star cast of the Milan Luthria directed action drama also includes Kangana Ranaut, Prachi Desai and Randeep Hooda.

Says an elated Ekta Kapoor, "I'm very happy with the response the film has received. The collections have been outstanding and all our hard work on the movie has borne fruit."
