Her stunning performance as mother of a dyslexic child in Aamir Khan-directed Taare Zameen Par (2007) won her all-round praise and numerous honours, including a National Award.
"Now I want to do something different. I want to play a baddie," Tisca said here.
She will be yet again playing the role of mother in 'Ankur Arora Murder Case', an upcoming Bollywood thriller directed by Suhail Tatari and written by Vikram Bhatt.
"I was frightened to do this film. Initially, I was little sceptical. I couldn't forget that the child has died in this film...I used to get scared at this thought and would wake up at 2 AM," Tisca said.
