Abhishek Bachchan, who was eagerly looking forward to see his father Amitabh's performance in "Teen Patti", says the veteran actor just keeps getting better with every film even at the age of 68.

"'Teen Patti' releases today. Can't wait to see what Big B has in store for us this time round. (I am) still getting over his performance in 'Rann'. He's just this force that has become unstoppable! Shocks you with every new performance...full power to you Pa, " Abhishek posted on Twitter.

"He's a 68-year-old giving this current generation a run for their money. Highly doubt any of us will be able to do the same at his age, " he added.
