"There's a lot that we have to learn from South because the way they work, we have to understand a lot now. They work in unity and respect each other's talent, we have to learn that," he added.Hosted by filmmaker Karan Johar, actor Rana Daggubati and RJ Balaji, the audio launch of the film was also attended by Rajinikanth's family, including his wife Latha, daughters Aishwarya and Soundarya, and son-in-law and actor Dhanush among others.
