Over 200 films from as many as 58 countries will be screened over a period of seven days.

Shyam Benegal, chairman of the Mumbai Academy of Moving Images (MAMI), which organises the festival, said the films in the International competition for the first feature film of directors will be judged by an international all-women jury headed by New Zealand filmmaker Jane Campion.

MAMI will also honour two outstanding film personalities -- Academy award winner Oliver Stone and noted filmmaker Manoj Kumar -- at the end of the festival, he said.

The personalities will be honoured with the lifetime achievement awards, Benegal said.
