Dipannita, 37, who was last seen in a supporting role in Bipashu Basu starrer 'Jodi Breakers', said she took the role as a challenge.
"It was a challenging path for me to take up the role. It required guts to play a paranormal character. This is a role which demands not to look pretty onscreen. It was a change for me because audience have not seen me in such a role. I am really excited and looking forward to the release of the film," Dipannita told PTI.
Dipannita said she was not scared to play the role because she herself is a huge fan of horror films.
"I have a huge collection of horror films. I not only watch famous Bollywood and Hollywood horrors but films in other languages too. The best thing about 'Pizza' is that it's a new subject of supernatural thriller which has not been explored yet," she said.
But the former supermodel insists that she didn't watch the original Tamil film of the same name.
