Prithviraj had a very special birthday, this year.

As he celebrated his 25th birthday on the 16th October in the sets of 'Kangaroo', he was seen more than happy to deliver the biggest hit of his career in 'Chocolate', released this season.

The film which amassed around two crores from the first week itself is all set to be the chart topper for at least another four weeks, till the arrival of new releases.

And for the first time, Prithviraj is earning all the credits for the film as he has used his soft lighter characterizations in many a sequences to bring in desired chuckles. The film is running successfully in around 40 theatres in the state with 90 percent collections, and is expected to become one of the biggest hits of the year after 'Mayavi' and 'Hello'.
