Bachchan, who paid a visit to the Oxford University on Tuesday, said he saw some "incredible manuscripts they have preserved in their archive - the Magnacarta, translations of Shakuntala. I also saw Kalidasa, and the very first manuscript of print edition of Shakespeare's plays.

"It was very educative to know, they have taken such a keen interest in Indian languages, Indian philosophy and Indian religion. It was a very exciting day."

Big B, who was here to launch his voice blogging service, Bachchan Bol, said he started his voice blog in India a year ago which helps fans find out more about his life.

"Bachchan Bol empowers me with a personal platform on which I can connect and 'speak' directly with my fans across the country anywhere and anytime.

"This is my bol/diary... my way... from my films to my family, from my country to my city, who will be able to hear about it all, in my own voice, in my own diary, direct to you on your mobile phone," Bachchan said.

There are already 2.5 million subscribers to Bachchan Bol in India which is expected to grow to 10 million in the next six months.

Asked about his forthcoming films, Bachchan said, "There are two - 'Buddha Hoga Tera Baap', a light hearted film made by Puri Jagannath. He is a prominent Telugu film director, who is making his first Hindi Film.

"The film is ready for release around July 1. It stars Hema Malini, Ravina Tandon, Sonu Sood and myself. The music by Vishal-Shekhar.

"The other project is Prakash Jha's 'Arakshan'. It is on the education system in the country and it covers many aspects of what reservation means now."

Asked how he sees the future of Bollywood, Bachchan said, "There is more recognition worldwide for Bollywood. We have the largest clientele - 3.8 billion against 3.2 for Hollywood.
