The film was made under the banner of Esso World Theater at the request of a non-profit American public broadcasting television, PBS.  It was made as part of a trilogy of short films from India.  The other two films in the trilogy featured Indian Sitar player, Pandit Ravi Shankar and a Ballet troupe from Mumbai, then known as "Bombay".  Ray, who worked prominently for Bengali cinema, was requested to make a film in English language with a Bengali setting, however Ray being an admirer of silent film decided to make a film without any dialogue as a tribute to the genre. The genre of science fiction has been prevalent in the Indian film industry since the second half of the 20th century.  Beginning in 1952, the film "Kaadu" was made, which was a Tamil-American co-production. " The Alien" was a science fiction film under production in the late 1960s which was eventually cancelled.  The film was being directed by Bengali Indian director Satyajit Ray and produced by Hollywood studio Columbia Pictures.

In 1987, the superhero film "Mr. India" was a huge success which strengthened the hold of sci-fi films in India, especially Bollywood.  "Indiatimes Movies" ranks the movie amongst the "Top 25 Must See Bollywood Films".  "Mr. India" brought the idea of science fiction to the general people in India.  In 2003, the blockbuster film "Koi... Mil Gaya" marked the beginning of the successful Krrish film series, which is the first sci-fi/superhero film series in Indian cinema.

On 20 September 1977, it finally premiered at the New Empire theatre in Kolkata, India.
