On Mani Ratnam's 67th birthday, actor-politician Kamal Hasan penned a note for the filmmaker, whom he called "doyen of Indian cinema who has touched the hearts of millions."

Kamal, who lent his vocal prowess to Ratnam's 'Ponniyin Selvan 2', took to Twitter to pen the note: "If one were to count life by the happiness that they create around them and if age is calculated by the friends around you, my dear #ManiRatnam you are going to be a much older man today! A doyen of Indian Cinema who has touched the hearts of millions through his art and one who transformed dialogues into a lovely visual experience."
