As the blame game is on following the poor performance of Mammootty's Vishu release Doubles at the box-office, the scriptwriters of the movie ,Sachi-Sethu are likely to part ways.'Doubles' and the movie on production 'Seniors'will be their last films together, as per the reports flowing in from Mollywood. The scriptwriter duo will now separate and will start writing separately for different films.

Sethu will start scripting for Prithviraj starrer 'Mallu Singh' to be directed by Vysakh while Sachi will get busy with the Joshy's yet to be titled Mohanlal film.

The young scriptwriters were much applauded for their debut hit 'chocolate' which came up a few years ago.Their next hit was 'Makeupman' with Jayaram which is currently on theatres.But their Vishu offering 'Doubles' invited huge share of criticism from masses and critics alike due to its lack of any plot , poor dialogues and very old narrative structures.As per the initial reports 'Doubles' may find it hard to be on the safer side in the Box Office.
