New Delhi, July 15 (IANS) Bollywood scriptwriter Abbas Tyrewala, who has created waves with his directorial debut 'Jaane Tu...Ya Jaane Na', a romantic comedy, is now racking his brains for his next movie, which he says wil be a 'naughty adult comedy'.

''Jaane Tu...' was a fairly clean film and catered to 21-year-old people. Although I couldn't get down with the idea of a 21-year-old not knowing about sex, I wanted my first to be a very family movie,' Tyrewala said.

'But I want to get naughtier in my next film. I will be raising the age bracket of my audience to 28 and 30-year-old. Through that, I want to tell people that when the heart breaks, it breaks seriously,' Tyrewala said.

He was in the capital Tuesday on the sixth day of the ongoing 10th Osian's-Cinefan Film Festival of Asian and Arab Cinema.

His 'Jaane Tu...Ya Jaane Na', released July 4, is a light romantic college drama that marked the debut of Aamir Khan's nephew Imran Khan.

The film had opened with a 100 percent collection across India. Its box-office collections from 40 locations abroad was approximately $1.3 million (Rs.50 million) till Sunday, according to UTV, which has released the movie worldwide.

Tyrewala was caught unawares by the international collections of 'Jaane Tu...' and in appreciation of the figures, he said: 'The international audiences are accepting the Indian sensibilities'.

He said: 'I hoped that the film will do well. The vibes on the sets, the fun and music - all of it gave me positive vibes as the film was meant to be a fun story.

''Jaane Tu...' has a real sensibility and I always kept on telling people even before the release of the film to watch it in a group as it would be more fun. And the best thing that happened was that the audience kept on coming back in groups.'

After the success of his film, Tyrewala has no plans to write for anyone else in the industry anytime soon.

'I don't think I will have the luxury of writing for anyone else as of now. It takes me around six months to a year to work on a script but then if I do it for other people, I won't be able to work on my projects and I am really itching to direct again,' Tyrewala shared.

The filmmaker says he 'did not set a legend with 'Jaane Tu...'. However, he promises that each of his films will be one of a kind.

'The day I make a film which is not audience friendly, I will tell the media that the film is for myself and please don't watch it,' he quipped.
