Sunil Kumar, who gained fame for playing Sarkatta in 'Stree 2', was also Amitabh Bachchan's body double in 'Kalki 2898-AD'. Speaking about his first day on the set, he recalled that Amitabh came up to him and asked the camera person to click a picture with him. "He...said, 'Everyone calls me tall, but I...finally met someone...taller than me'," Sunil said.
