When you are working with somebody like that, you take a lot from them and that helps you to perform well because you are constantly being challenged," he added.Vidya on the other hand was nervous shooting with Farhan after watching his impeccable act in ‘Bhaag Milkha Bhaag'."It was wonderful working with Farhan. I must say that of course, I knew his work. I had watched his films. But I was very happy I watched 'Bhaag Milkha Bhaag' after our shoot was over”, said Vidya while interacting with media during trailer launch."I couldn't have gone back on the sets after having watched that film. I couldn't have performed with him after that film," she added."Shaadi Ke Side Effects" which is a sequel to his 2006 flick "Pyaar Ke Side Effects" is directed by Saket Chaudhary and will hit the screens in February next year.Catch all the other pics from the trailer launch.
