Jaya Bachchan called out the credits at the beginning of the movie. Ironically, this was done by her husband Amitabh Bachchan for her film Bawarchi (1972).
The movie is inspired by Sam Berns' life.
Taruni Sachdev who plays Auro's classmate died in Agni Air Flight CHT plane crash in Nepal on her 14th birthday.
This film was inspired by Jack (1996), making it the second film to star the Sr.-Jr. Bachchans that has been based on a Francis Ford Coppola film. The first was Sarkar (2005), which was based on The Godfather (1972).
This is the second time Amitabh Bachchan draws inspiration from a Robin Williams film. The first was Aladdin (1992), which inspired Bachchan's performance as Genius in Aladin (2009). This film was inspired by Jack (1996), which stared Williams in the eponymous title.
