Upon arriving on the films sets, Raaj Kumar realized that Dilip Kumar's character spoke Hindi with a U.P. BIhari dialect. This angered him as he was to speak regular Hindi in the film and he was not told about Dilip's characters Hindi. He told Subash Ghai he was quitting the film right there and then and returning back to Bombay. Subhash Ghai had to go and convince Raaj Kumar for two hours to remain in the film. Ghai reasoned that Raaj Kumar's character was rich and royal where as Dilip's was a poor lower cast character. Hearing this Raaj Kumar finally relented and stayed in the film.
