i do not claim to be an expert in bengali literature ( far from it ) and but i have always find story come out of bengal to be a class apart . the characterization and the depth of the plot and the sincerity of the human emotion in those story be the among the fine to be find anywhere . kabuliwala be another such great movie to be base on a bengali story . sharmila tagore be superb and vinod mehra play the grow up nandu with great sincerity . rajesh khanna lend a lot of credibility to anand babu despite have turn a major superstar during the making of this movie . om prakash be always a pleasure to watch although his role be very small . r. d. burman and kishore kumar top it all off with the great music .
