We normally hear that young actors who are sons of big directors and established actors, work for an year or so, with star directors of their generation as assistants or at some other capacity in their films.
Mainly, Karan Johar, the producer and director from Hindi, feels proud to accept such 'star' students. Varun Dhawan, Siddharth Malhotra and many others worked as assistants to him.
Ranbir Kapoor worked as an assistant to Sanjay Leela Bhanshali, before the director launched him with Sawaariya. Abhishek Bachchan too assisted J.P. Dutta, before, Refugee.
In Telugu though, actors send their sons to Satyanand school in Vizag or to an International Institute, to train them as actors before launch. On contrary, Varun Tej, worked as Puri Jagannadh's assistant before he made up his mind to act in films.
Varun Tej revealed, "I was a one day assistant director to Puri Jagannadh while he is making Chirutha. I did not know what I should do in films and never had a clarity of thought as well. My father asked me to try direction and joined me with Puri Jagannadh's team, while making Chirutha. I could go and work only for one day and stopped afterwards. Puri Jagannadh, met me after few days and told me that he always thought, I will be an actor and not director. I am happy that in the film of a director, I assisted, I acted as a hero."
Chiranjeevi encouraged the young actor to find his passion in acting and he is known going great with two back-to-back successes, Fidaa and Tholiprema.
