Expendables 3 starring Sylvester Stallone, that released last year, was shot in the South-East European film studio two years ago. And now, Shah Rukh Khan, Kajol, Varun Dhawan and Kriti Sanon will film action sequences for Rohit Shetty's upcoming venture Dilwale that releases this year in Christmas.
Meanwhile, Rohit has brought in a few cars and a swanky bike for the scenes in question. The quartet starts shooting in a day or two.
