Prithviraj is playing architect Roy Mathew in Arjunan Sakshi. The story of the film revolves around a young architect, who has spent his entire life abroad, arrives at Cochin with dreams of starting a life afresh. But he soon realises that the city that he gets to live in is radically different from the one that he had seen in his dreams.
Ann Augustine is said to be appearing as lead lady in Arjunan Sakshi. And Biju Menon, Jagathy Sreekumar, Nedumudi Venu, Suraj Venjaramood, Vijayaraghavan, Salim Kumar, Vijeesh are in other cast. Anil Panachooran has penned the lyrics and Biji Bal has composed music for the film.
However, Prithviraj's previous releases like Anwar and Thriller, which were much-hyped movies, were avarage hit at the Box office. Now, Arjunan Sakshi is his first release in 2011 and it is very crucial movie for him. So Prithvi has lots of expectations from this flick.
