Bachchan took to Twitter and shared a tweet by a fan, which had pictures of Agastya and the other two star kids set to make their debut with the film- Shah Rukh Khan's daughter Suhana Khan and Sridevi's younger daughter Khushi Kapoor.
"Agastya... A new chapter begins in your life and there cannot be greater joy among us all. My blessings my love and my wishes ever .. Do well .. And keep the flag flying," the 79-year-old wrote.
The Archies is produced by Akhtar and her longtime collaborator Reema Kagti under their production house Tiger Baby. Suhana will be seen playing Veronica Lodge, while Khushi will feature as Betty Cooper.
