Kasak

Mouna Ragam was heartwarming with fantastic music. Kasak, on the other hand, lack all the qualities that made the original great, despite being a frame by frame copy.

First of all, this movie shouldn't have been made. The original movie by Maniratnam was far better than this.

Kasak clearly lacked technical finesse of the original Tamil film. Mouna Raagam had music was composed by Ilaiyaraaja, with lyrics by Vaali. P. C. Sreeram was the cinematographer, and the art director was Thota Tharani. The film was edited by B. Lenin and V. T. Vijayan.

Mouna Ragam was released on 15 August 1986. Despite opening to modest audiences, it became a box-office success, with a theatrical run of over 175 days, and Mani Ratnam's breakthrough. The film received critical acclaim; it won the National Film Award for Best Feature Film in Tamil, and Ratnam received the Filmfare and Cinema Express Awards for Best Director in Tamil. Mouna Ragam also became a breakthrough in Karthik's career despite his role being a cameo. The film introduced techniques such as soft-focus shots, flare filters and backlighting, which became popular in Tamil cinema.
