New Delhi, July 31 - One of Bollywood's most successful comedy makers directors, David Dhawan, says a filmmaker has to be emotional to make a good movie. He also admits to getting stressed even now before the release of each of his films .

'If you don't know how to cry or laugh, then you can't understand the audience. The goodness has to be within you to come up with something exciting. A good movie should have the right mix of emotions, backed by a powerful script,' Dhawan told IANS here.

Dhawan's upcoming 'Do Knot Disturb' is again a lighthearted romantic comedy that stars Govinda, Riteish Deshmukh, Lara Dutta and Sushmita Sen. It is scheduled for a September release.

He is also working on another project titled 'Hook Ya Crook' that stars John Abraham, Kay Kay Menon, Shreyas Talpade and Genelia D'Souza.

After teaming up with stars like Govinda, Anil Kapoor and Salman Khan in several hits, Dhawan now wants to make a movie with animals as protagonists.

'I love animals and I want to make one movie with them. I have always wanted to make a movie with animals, but for that you need a trained animal and lots of patience too,' said Dhawan, who used a chimpanzee in 'Aankhen' and a dog in 'Biwi No.1'.

He confesses he was under extreme stress before the release of his first hit, 'Shola Aur Shabnam' (1992).

'I must admit that 'Shola Aur Shabnam' was my last chance to prove myself as a director.
