From Sholay to Pathaan, brilliantly executed action sequences in running trains have always fascinated audiences.
Director S Shankar, whose Enthiran/Robot with Rajinikanth featured one such scene, is set to up the ante with his next, Indian 2, starring Kamal Haasan.
Next week, the director and the actor are reportedly heading to South Africa for a 14-day schedule, during which they will film the marathon action sequence in a train.
It is touted to be one of the highlights of the thriller, a sequel to their 1996 outing, Indian.
