My selection is:
1-Black: Though a dark movie and not made for everyone, but I think it had some superb acting by the great acting along with rani and little ayesha
2-Anand: Though heavily dominated by the then superstar Rajesh Khanna, Amitabh made his mark by his superb acting in a phenomenal movie.
3-Namak Haram: Again great acting in a great movie.
4-Aks: People did not like this movie though I thought it was a very slick movie with great acting by the Big B.
5-Shakti: Vow....we dont get to see the best actors of hindi cinema in 1 movie and probably will never get I again. Dilip Kumar, Amitabh, special role by Anil Kapoor and great acting by Rakhi, topped with great direction by Ramesh Sippy, excllent story by Saleem Javed and music by none other than the great RD burman. Dont forget the best villain in it....amrish puri
6-Virrudh: I think amitabh’s acting in this very well made movie was astonishing. This was an underrated movie.
7-Sholay: Who can forget his on screen rapport with dharam in this very garam movie...a must watch
8-Mein azad Hoon: Not too many people know about this movie...i consider this as his all time great. Great story line by Javed Akhtar.
9-Sarkar: I consider his acting good in it, however the when compared to the original product ’’godfather’’ the movie looks very pale and that is the downside of this one.
10-Saugadar: A very less known movie but I think it was failry good
11-Alaap: I loved this very different movie on a very different topic.
I am not including a number of other movies as the list goes on. However against the common notion, I am not a big fan of his regular 70s and 80s manmohan desai kind of entertainment which I thought was not a great show of his acting capabilities. I think the present genre of directors a doing much more justice to him as an actor. I know I am going to anger many people by saying this....though I loved those movies at the time they were made....which proves that those movies were for kids only.
