Ranveer Singh has gained significant attention for his role in the successful 'Dhurandhar' series. Director Anurag Kashyap recently shared a revealing anecdote about Singh's extreme dedication while filming the 2013 movie 'Lootera', where he portrayed a wounded character. To achieve authenticity, Singh fastened a clip around his stomach to experience real pain, which ultimately led to him needing medical assistance. Kashyap noted that this incident reflects Singh's deep commitment to his craft, a trait that has been evident throughout his career. While 'Lootera' did not achieve the same box-office success as 'Dhurandhar', Kashyap emphasized its importance in showcasing Singh's determination and passion for acting.
