Gone are the days when celebrities resorted to charity activities on their birthday, to garner attention. With every actor turning benevolent even off season, the trend now is to publicize their movie on their birthday. The latest to join the band wagon is actor Karthi, who celebrates his 36th birthday on 25th May. Marking his celebration, the 'Biriyani' team has decided to release their teaser on the actor's birthday. Produced by Studio Green and directed by Venkat Prabhu, 'Biriyani' stars Karthi, Hansika, Ramki and Premgi, among others. Apart from Ramki's comeback, there is yet another note worthy feature in the film, for this is Yuvan Shankar Raja's 100th musical. We wish actor Karthi and the 'Biriyani' team a fun filled time on the actor's birthday, with the release of one of the most awaited teasers of this year. Karthi is also acting in yet another comedy caper, 'All In All Azhaguraja'.
