Young star Agastya Nanda, grandson of iconic actor Amitabh Bachchan, turns 24 today and has already received birthday wishes from friends and family, including a playful jab from Shah Rukh Khan's daughter Suhana, who herself made her Bollywood debut with Nanda in the musical 'The Archies'. Nanda's 'Minnie-Mouse-ing' with his sister Navya Naveli Nanda, who also posted a collage of the two of them as kids and them imitating them today, is a delightful 'then and now' for the fans. Meanwhile, Nanda has been signed up to act in Sriram Raghavan's biopic of 1971 War's Arun Khetarpal PVC. Khan doesn't have the luxury of acting with her dad in this, since she is reportedly on for a Sujoy Ghosh starrer titled 'King'.
