Side effects are funny, sometimes they are a wonderful surprise, and sometimes they are a mixed bag. One can only imagine that marriage would come with side effects... Pleasure being replaced by companionship... Lovers becoming friends... But not Sid (Farhan Akhtar) and Trisha (Vidya Balan). Theirs is a shaadi where they are living out each other's fantasies, turning them into reality peppered with love, lust and longing. Shaadi Ke Side Effects is a witty, sexy comedy that re-defines happily ever after - if there really is one!!
