The veteran actor will be shooting for the climax of the action fantasy adventure.Mirror (October 17) had earlier reported that Ranbir Kapoor and Alia Bhatt will fly to Manali in November for a 15-day shoot of Ayan Mukerji’s Brahmastra . Earlier this week, the duo was spotted at the airport leaving for the resort town. Ranbir’s right arm was in a sling after an injury he reportedly suffered while playing football on Sunday. Alia was later spotted in a Himachali topi while RK sported a beanie as the locals welcomed them. Amitabh Bachchan, who plays Ranbir’s guru in the action fantasy adventure, joined them on Wednesday.According to a source close to the development, they are shooting for a larger-than-life climax, with the Big B in a strong supportive role for Ranbir’s Shiva who can emit fire from his palms. “Amitji is in Manali, for the next few days before he moves to another shoot in a foreign location in early December. The film’s antagonists, Mouni Roy and Saurav Gurjar, , too, will be a part of this schedule, that requires some amount of prep before the camera rolls,” informed the source.
