Big B took home a clutch of Best Actor awards for his role as the precocious Auro, a 12-year old with progeria, a rare disorder that ages his body at five times the normal rate. His father, played by Amitabh’s real-life son Abhishek, is an aspiring politician and had no idea he was a dad because Auro’s mother, played by Vidya Balan, kept it secret from him. Fate has other ideas, however, and father and son are united, as the clock ticks on the boy’s limited time left.
