Talking to IANS, Kabir, who is known for his directorial work on '83' and 'Bajrangi Bhaijaan', spoke about choosing Kartik as 'Chandu Champion'. The movie is based on India's first Paralympic gold medalist, Murlikant Petkar. Kabir told IANS: "When I was writing the script of 'Chandu'... obviously, when you are writing the script, you have an image in your mind. And that image, that character, has an age, personality, attitude... So, when you have these pointers, the next step is to identify which actor can embody all these characteristics. Very strongly, I felt those characteristics in Kartik Aaryan." "We have never worked before, not even met properly. Then we had a meeting for around 2.5 hours, during which we had a lot of conversations about the film. As a director, during our talks, it's my job to gauge whether he is the right fit for this character. A director's gut instinct is very strong. After that 2.5-hour meeting with him, I was very clear that Kartik would be the 'Chandu Champion'," shared Kabir.
