That Ayan Mukerji meant business when he said Brahmastra will involve action was made evident when he roped Israeli movement coach Ido Portal - among the most celebrated names in movement culture across the globe - to train his cast. While lead actors Ranbir Kapoor and Alia Bhatt spent a fair share of time learning from Portal earlier this year, mid-day has it that the film's antagonist, Mouni Roy, is leaving no stone unturned to give them tough competition.

Roy, who also learnt from Portal for a brief period, is set to pull off action sequences for reel for the first time. However, it is under the guidance of trainer Kuldeep Shashi that she has been undergoing intense prep for her part. A source close to the production tells mid-day, "As a villain, Mouni is expected to be lithe, agile and fast-footed. She has been training in free-running and gymnastics with Kuldeep since January, and has also been working on her flexibility." While Roy's portions won't involve martial arts, she will pull off hand-to-hand combat sequences, apart from high-octane gymnastic moves like free-wheeling spins, back flips and splits, says the source.
