Filmmaker Imtiaz Ali said Diljit Dosanjh didn't sacrifice a single hair for 'Amar Singh Chamkila'. "Diljit has worn a wig. That wig is like his turban only...He knew how Chamkila looked, so he managed to look the part with a wig," Imtiaz told Radio Nasha. Diljit had earlier said he won't do roles which require him to not wear turban.
