Which is the best film of Amitabh you think?

I like Sholay and Deewar, best old movies. He is extraordinary in these movies compared to others.

I think black is his best film... Amitab bachan,the man without comparison,he is the eklavya in bollywood,he is making aag in the film industries.....what a man....His sound makes me always crazy about him...His personality attracts me towards...I am not his fan still he is in my heart...I shocked with his mind blowing performance in black..He got national award for it..Amitab has his own identity in the indian film industry...Nowadays a film without him cannot reach the completion...
