Karan Johar proud of Sidharth, Varun and Alia

Filmmaker Karan Johar, who launched actors Alia Bhatt, Sidharth Malhotra and Varun Dhawan in Bollywood six years ago with Student of the Year, says he is proud of how they have shaped up.

On the completion of six years of the Punit Malhotra directorial on Friday, Karan became nostalgic and thanked the actors for making the film a blockbuster. "So Proud of Sidharth, Varun and Alia. Love you and thank you for making this film so special for all of us at Dharma Movies," he wrote on Twitter.

Student Of The Year was a film about friendship and love told through the story of three college friends.

Karan's production company Dharma Productions and Punit are now coming up with a sequel to Student of the Year. It will launch actor Chunky Pandey's daughter Ananya and ballet dancer Tara Sutaria, who will star alongside Tiger Shroff.
