Ronit Roy injured himself during and action scene and required surgery following which nine pieces of glass were taken out from his arm.
The movie features a recreated version of the classic song "Sara Zamana" from Yaarana which featured Amitabh Bachchan. Co-incidentally, it's a Rajesh Roshan song.
