The film's unit, currently in the picturesque locations of Ranikhet, did not brace themselves for so many retakes of the scene.
The movie's associate director Anshuman Jha is said to have pulled up the actors for not enacting the scene passionately, said a source.
After a continuous 37 retakes, Ghai finally canned the shot.
"Kaanchi", a musical thriller, will release in August.
Ismail Darbar and Salim-Suleiman have contributed to the tunes of the film, which also features Rishi Kapoor and Mithin Chakraborty.
