Veteran actress Padmini Kolhapure shared that her biggest regret in her nearly 50-year-long acting career is that she missed out on working with actor Amitabh Bachchan. "I've worked with everyone...Amitabh is the only actor I haven't worked with," Padmini said. The actress was reportedly the original cast of 'Silsila' alongside Amitabh, but her role eventually went to Jaya Bachchan.
