'Dhamaal 4', starring Ajay Devgn, Arshad Warsi, Riteish Deshmukh and Jaaved Jaaferi, has opened to a strong response at the box office, riding on the nostalgia of the nearly two-decade-old comedy franchise. After a Day 2 net of Rs 22.50 crore, marking a 60.7% jump from opening day, the film has entered Day 3 with live tracking showing it inching towards the Rs 50 crore India gross mark within its opening weekend itself.
