The late filmmaker Kamal Amrohi's grandson Bilal Amrohi makes his Bollywood debut in Atul Agnihotri's upcoming production, O Teri.

Bilal, who has grown up watching his grandfather's films, says his favourite is not Pakeezah, but the 1949 film Mahal starring Madhubala and Ashok Kumar.

He thinks Mahal set the trend for suspense movies with supernatural elements.
