Bollywood's current hearthrob Ranbir Kapoor, who plays the male lead in Rajkumar Santoshi's recently released hit romantic comedy "Ajab Prem Ki Ghazab Kahani", is all praise for him and says that the filmmaker is an institution in himself.

"It was great that I got to work under Mr. Santoshi who is an institution in himself. Every actor should work with him at least once because the amount of confidence he instills in an actor is amazing, " Ranbir told.

Santoshi has helmed films like "Ghayal", "Damini", "Pukar" and "The Legend of Bhagat Singh", among others.
