Farhan Akhtar, actor and filmmaker is of the view that a comedy should never be over rehearsed as it was likely spoil the outcome.

Farhan says, "As far as acting is concerned you draw everything from the script and follow the director. In terms of comedy you can't over rehearse things as it takes away from it. The script, the lines have to be witty."

Farhan is teaming up with Vidya Balan for the first time and is playing reel life couple in romantic comedy 'Shaadi Ke Side Effects'.

"Marriage is a relationship between two people like friendship and partnership. Everything in life is work in progress...you get to know each other constantly. Not every day will be amazing...you won't be seeing eye to eye but if you care and love each other everything will be well," Farhan said.

Farhan, who is happy about his marriage to celebrity hair stylist Adhuna Akhtar, is excited to share the screen space with Vidya.

"As an actor and director you want to work with people who are good at their work and are hungry for it (work). She is a strong and better performer. So it challenges you to do more better as an actor. It was wonderful working with her," Farhan said.
