Farhan Akhtar and Vidya Balan had to give 21 retakes for one scene for their upcoming film Shaadi Ke Side Effects.

It was an emotional scene, but they would end up giggling resulting in takes after takes. Director Saket Chaudhary says, `I really don't remember the number of takes, but it was Vidya who first started breaking into a laughter and then Farhan did the same.

It went on for some time till they regained their composure to give the scene to be okayed by me.''
