, Bhumi Pednekar showered love on AB's post. During an interview with ETimes, Abhishek was asked about comparisons with his father and if he ever thought in his 23-year old movie journey if people were unfair to him. Reacting to it, Abhishek had said, "I have a very different way of looking at things. The way I looked at it, is that you're comparing me to someone I consider the best actor in the world. If I'm worthy of being compared to him means I'm doing something right. I might not be there entirely but if you're speaking about me in the same ballpark as Amitabh Bachchan, I might be doing something right. I looked upon it more as an appreciation."
Big B had a cameo in Abhishek's recent film '

Ghoomer

', however, the father-son duo didn't share screen space in it.
