Director Roshan Andrews, whose latest film, ‘Ividam Swargam Aanu’ with Mohanlal was a hit, has now signed on Mammootty for his next film.

Produced by Carlton Karunakaran, the film is said to be a mystery/thriller. Bobby-Sanjay will be scripting it. They have earlier worked with Roshan on ‘Notebook’. The Mammootty starrer film will start filming towards the end of 2010.

Roshan, in the meantime, is ready to start off his next film, ‘Casanova’, with Mohanlal in March.
