In the later half of his career, NTR became a screenwriter. Despite having no formal training in scriptwriting, he authored several screenplays for his own movies as well as for other producers. He also produced many of his films as well as other actor's films through his film production house National Art Theater Private Limited, Madras and later Ramakrishna Studios, Hyderabad. He actively campaigned for the construction of a large number of cinemas through this production house. He was influential in designing and implementing a financial system that funded the production and distribution of movies. He was so dedicated to his profession that he would often learn new things in order to portray a particular character on-screen perfectly and realistically. At the age of 40, he learnt dance from the renowned Kuchipudi dancer Vempati Chinna Satyam for his role in the film "Nartanasala" (1963).
