"I am stepping into art films with 'Bits and Pieces'. The film will see me in a very different light," Dia said at a promotional event here Thursday evening.
Though the actress refused to divulge details about her role, she revealed that the film was set in a mental asylum and has her "thrilled and excited".
Dia, who was last seen as a reporter in "Shootout at Lokhandwala", said she was now concentrating on doing "good cinema" even if the length of the roles were small.
"In the last two years, I have tried to work in good films without looking at the length of the roles. I think more people have seen my work in this period. It is much better than doing a lot of stupid films."
The model-turned-actress will be next seen in "Cash" where she tries her hand in comedy. "I am trying different roles. While in 'Cash' I play a comic role, the film 'Crazy 4' will see me playing a reporter again. My other movies are 'Alibaug' and 'Dus Kahaniyan'," she said.
Dia also disclosed that she has voted over 60 times for the inclusion of Taj Mahal in Agra into the new list of Seven Wonders of the World. But she remained tight-lipped about rumours of her affair with the macho actor Kunal Kapoor.
"I am not going to speak anything (about it)," is all she said. The former Miss India said the production house was the most important criterion for her while choosing a film.
"The production house is important because I have to judge whether the producers have the capacity to carry off a film. Then comes the script and then the director," she said.
