Ajay Devgan's upcoming movie 'Drishyam'

In the Goa-set murder mystery, Devgan, 46, plays a family man and is pitted against Tabu, who will be seen essaying the role of a cop in search of her son, presumably killed by the former. 'I cast Tabu as I wanted someone, who is a mother at heart and a very strong cop. Someone, who is both vulnerable and strict. Tabu was my first and last choice,' the director said.
