For a promotional event shoot for Nadunisi Naaygal at AVM studios yesterday, Gautham invited stalwart director Bharathiraja for a special interview. Gautham Menon has said that the first psychological thriller in Tamil cinema 'Sigappu Rojakkal' was such a cult hit, that today the movie has become synonymous with the genre itself. The two directors who share a fantastic rapport had a great time and were seen laughing on many an occasion. Its good to see directors from different generations share such mutual respect and admiration for each other. Right from the beginning, Gautham Vasudev Menon is sticking to the brand of 'Sigappu Rojakkal' as the film happens to be the one and only best thriller ever made in Tamil Cinema since 1978.
