Raju Hirani writing another hit?

Mumbai: After the stupendous success of `3 Idiots`, filmmaker Rajkumar Hirani has started work on yet another script but refuses to reveal any details.

"I am writing a script and hopefully next year I will start making my film, but it is too early to talk about it," he said.

So far Hirani has scripted box office blockbusters only -- his `Munnabhai series` raked in moolah at the box-office as did Aamir Khan-starrer `3 Idiots`.
