Mumbai -- Multilingual actress Revathy is very happy with the growing interaction between Bollywood and Southern film industry with a host of regional films being remade in Hindi and vice-versa. "It's one country. The issues and emotions are very much similar. The beauty about India is that it's so varied, the cultural differences, the language differences and the way people think. It is interesting for filmmakers to try and cater to that particular region in a different way," Revathy told IANS. She added, "You have a pan-India audience, you have very regional audience and it's beautiful to see the way things are coming. It's like the world becoming smaller and boundaries are slowly getting wiped out".
