Varun found shooting for action-packed 'Dishoom' difficult

New Delhi: Bollywood actor Varun Dhawan, who will be soon seen in 'Dishoom' alongside John Abraham, revealed that it has been a very challenging flick for him. The 28-year-old actor said, "It has been a very challenging film because there is a lot of action in the film. John and I have been through some really dare-devil stunts." "I am actually very thankful to have a co-actor like John because when you are doing action and when you are risking your life for these things you need someone who has your back. Every stunt we had John would try it first then asked me to do it," Varun added. The 'Badlapur' star, who faced many injuries during the shoot of the flick, also revealed that he even passed out while shooting one stunt. Varun also claimed that all the stunts that will be seen in the film have been performed by him and John and no body-double or special effects have been used. The flick that also stars Jacqueline Fernandez in lead role is being produced by Sajid Nadiadwala.
