"Wishing a Very Happy 71st Birthday today to Amitabh Bachchan - the man who has made a habit of redefining the meaning of the word 'Legend'," Mamata, known for her love for Indian cinema, said in a Facebook post.
"Rarely does someone combine fame and humility with such nonchalance, charm everyone without a wand, and deliver awe-inspiring performances so regularly. His magnetic personality continues to attract people of our country and abroad with effortless ease," she said eulogising the superstar who has mesmerised the world of Indian cinema since the 1970s.
