Filmmaker Karan Johar is known for his romantic films and family dramas, but now he is keen on making a biopic and that too on late legendary actor, director and producer Guru Dutt.

Says KJo, "Making a biopic is something I am really excited about, but it should be on someone who interests me. While it would be challenging to project one's life on celluloid, the personality should be charismatic enough. I would love to make a film on Guru Dutt since I am a huge fan of his."

He further added, "I'd give years of my life to make a movie on him. He is my favourite director. No director can show love and romance the way he did. Guru Dutt's songs were so mesmerising that even today when I listen to them, kuchh kuchh hota hai."

Currently, the filmmaker is busy awaiting the release of his film 'Yeh Jawaani Hai Deewani' produced under Dharma Productions.
