Kartik Aaryan showed immense resilience while shooting for his upcoming sports biopic, Chandu Champion in London. Despite running a fever more than 101 degrees, Kartik opted to fly to London and shoot for the sports sequences, including the underwater ones. The film, directed by Kabir Khan, is based on the life and career of Indian athlete Murlikant Petkar. Kartik has undergone a significant physical transformation to play an athlete on screen. The film's shoot in London will conclude over the next few weeks.
