question:
Question: Did Rajinikanth and Sripriya star in any other films together? Passage:By the end of the 1970s, Rajinikanth had become a popular actor in South Indian cinema. During this phase of his career, he abruptly chose to quit acting, but was coaxed back. He made a comeback with the R. Krishnamurthy-directed Billa, which was a remake of the Hindi film Don (1978) written by Salim-Javed. The film was named after Billa, a real criminal. For the first time in his career, Rajinikanth was cast in dual roles: the eponymous gangster and the street entertainer Rajappa. Although the film was a shot-for-shot adaptation of Don, Rajinikanth avoided aping Amitabh Bachchan, the lead actor of the original, and instead interpreted the roles in his own unique style. K. Balaji played the role of the DSP Alexander, while Sripriya was signed to play the female lead which Zeenat Aman had portrayed in the original Hindi version. Jayalalithaa was earlier offered the role, but declined. Thengai Srinivasan was selected to play the role originally portrayed by Pran in Don, while A. V. M. Rajan and Major Sundarrajan played inspector Varma and interpol officer Gokulnath, respectively. Helen, who appeared in Don, reprised her role in this remake. Cinematography was handled by G. Or. Nathan, and the editing by V. Chakrapani. The film was produced by Balaji's son Suresh Balaje under Suresh Arts, while K. Balaji was credited as presenter.
