All big-budget movies of Kollywood are released by the market leaders Sun Pictures.
Their Maappillai with Dhanush, Manisha Koirala and Hansika Motwani is progressing briskly.
Sun Pictures is one of the most professional film producers in India. They follow the Hollywood pattern where the first copy of the film is seen by a competent team of studio executives, who make suggestions on how the final product could be improved according to certain specifications.
Similarly, they have a team dedicated to watch a film which they have picked up. After the film gets the final approval from this team, the marketing starts two weeks before release.
