The film won the National Film Award for Best Popular Film Providing Wholesome Entertainment and Shobhana was awarded the National Film Award for Best Actress for her portrayal of the central character Ganga. The film also stars Mohanlal, Suresh Gopi, Nedumudi Venu, Innocent, Vinaya Prasad, K. P. A. C. Lalitha, Ganesh Kumar, and Thilakan in the main roles. The music for the songs were composed by M. G. Radhakrishnan, and the background score was done by Johnson.
After its runaway success in Kerala, it was remade after nearly 10 years in various languages, including Kannada (Apthamitra), Tamil and Telugu (dubbed) (Chandramukhi), Bengali (Rajmohol), and Hindi (Bhool Bhulaiyaa).
