The Dharma Productions filmmaker has decided to break his vow of only working with established actors in the upcoming release, entitled Student of the Year.
"If I am nervous, I wonder what the three first timers are feeling?" Johar questioned.
Siddharth Malhotra, Varun Dhawan (son of David Dhawan) and Alia Bhatt (daughter of Mahesh Bhatt) have been cast in the lead roles.
The project arrives almost a decade after his last college-themed movie Kuch Kuch Hota Hai, and is reportedly inspired by the US television series Glee.
It was reported in January that the film's stars Dhawan and Bhatt are in a relationship.
