Music maestro Naushad Ali recorded the entire background music of "Aan" at the Royal Albert Hall, London; this is the first time the music for an Indian film was recorded overseas. Nadira was introduced in this film. This was the first Indian film in colour.

Nargis was the original choice for the role of Princess Rajshree before she dropped out and newcomer Nadira replaced her.
