Paropakari is a 1970 Indian Kannada language romantic drama film written and directed by Y. R. Swamy. It stars Rajkumar and Jayanthi in the lead roles. The film was produced under Bhagavathi Productions. It had a very successful soundtrack composed by Upendra Kumar.
Rajkumar plays dual role in this movie. Strangely, it is usually not considered among the movies in which he played a dual role because the 2nd character (that of a taxi driver) appears at the 52nd minute into the movie and dies at the 57th minute. However, the death of the second character is a necessary plot twist in the movie as after his death the lead character Mohan assumes the identity of the deceased character - Ramanna and moves into his house in order to create a false notion that Ramanna is still alive and thereby help the police identify the murderers of Ramanna and solve a burglary case also.
