There is a huge buzz around Amitabh Bachchan's 70th birthday, which falls Oct 11, but for the megastar, it's "just another day".

"A million interviews, a million good wishes and a million desires of continuance... birthdays at 70 seem special to some. Just another day for me," tweeted the 69-year-old veteran.

These days, he is busy meeting mediapersons for interviews, sharing insights and experiences of his life. Big plans are in store for his birthday, and his wife Jaya Bachchan, has reportedly planned each part of the celebrations including painting and poster exhibitions.
