Thyagaarrajan.During the making of the Rajesh Khanna starrer super-hit film Haathi Mere Saathi(1971),the producer Dhandayuthapani was part of the crew of the film as the office administrator and R.Thyagarajan was the editor of the film.Later in the mid seventies R.Thyagarajan became a very successful director in Tamil cinema with every film directed by him becoming big hits and all those films had Rajnikanth[8] in it as the lead hero.The producer and the director duo could not get much success in Hindi cinema with their films becoming duds at the box office until this film released.The duo then decided to direct a movie in Hindi in 1985 and made a casting coup of sorts by casting Rajesh Khanna and Rajnikanth in the lead roles[9].Dhandayuthapani produced only four films[10] in Hindi with Bewafai being the most successful of them.
