South superstar Kamal Haasan met renowned filmmaker Christopher Nolan and the actor was surprised to know that the director had seen his 2015 film "Papanasam".

Nolan, known for modern classics such as "Memento", "The Prestige", "Inception" and the Dark Knight series, is in India on a three day trip along with visual artiste Tacita Dean.

"Met Mr Christopher Nolan. Apologized for seeing 'Dunkirk' in the digital format and in return I am sending 'Hey Ram' in digital format for him to see. Was surprised to know he had seen 'Papanaasam'," Haasan tweeted along side a picture of him with Nolan.

Filmmaker-archivist Shivendra Singh Dungarpur, who is hosting Nolan for all the three days, hopes the director's trip to India will draw attention to the cause of film preservation and restoration.

A public lecture on 'Process and the Non-Deliberate Act' by Dean took place on Friday. It will be followed by a discussion on 'Reframing The Future Of Film' on April 1 in Mumbai with Nolan, Dean and Dungarpur.

A roundtable discussion is also planned with prominent personalities of the Indian film industry to be attended by Amitabh Bachchan, Shah Rukh Khan, Haasan, Shyam Benegal and others.

Nolan will be present for the screenings of two of his recent films Oscar-nominated "Dunkirk" and "Interstellar".
