Development After watching the
Telugu film
Dharmaatmudu (1983), director
A. C. Tirulokchandar told
M. Saravanan of
AVM Productions about his desire to remake it in Tamil; he wanted
Rajinikanth to play the male lead. Producer
K. Balaji had earlier attempted a remake with
Sivaji Ganesan, but dropped the project after feeling it was not suitable for Ganesan. Saravanan and others saw
Dharmaatmudu, and noticed how similar it was to the Tamil film
Hitler Umanath (1982). Screenwriter
Panchu Arunachalam objected to remaking
Dharmaatmudu since
Hitler Umanath was unsuccessful, but Saravanan and director
S. P. Muthuraman knew there was something responsible for
Dharmaatmudus success. Visu, in addition to working as screenwriter, also appeared as Vinod's father Gangadharan. The song "Vechukkava" was shot on a set resembling a five-star hotel with 200 television sets used. The song "Unnaithane" was intended to be shot at Kerala, but could not due to heavy rain there. Instead, it was shot at Muttukaadu due to its atmosphere resembling that of Kerala. The climax was initially very sentimental and, according to Saravanan, a poetic finish. The climax fight scene was shot at
Kallikottai, Kerala. == Themes ==
