A source says, "The film will be replete with action. And both Hrithik Roshan and Katrina will be performing power-packed stunts."
The source adds that the actors' previous films have been taken into account before handing out power-packed sequences to them.
The informer adds, "Hrithik's stunts from Krrish and Dhoom 2 are well known. And Katrina has been training in acrobatics and gymnastics for the third installment of Dhoom." Katrina is expected to perform a lot of stunts on the bike for which she will be trained by professionals who have travelled to India from the US.
Action director of Ek Tha Tiger and Rush Hour 3 Conrad E Palmisano will be training Katrina for her bike stunts.
