Director Rajkumar Hirani shared that Ranbir Kapoor can control his tear glands, a skill he used in the emotional scenes of ‘Sanju’, which was his biggest hit before ‘Animal’. Ranbir is now engaged in various projects such as ‘Ramayan’, Sanjay Leela Bhansali’s ‘Love and War’, ‘Animal Park’ and potentially ‘Dhoom 4’.
