Ramu is a 1966 Indian Tamil-language drama film directed by A. C. Tirulokchandar and written by Javar N. Seetharaman.

Raja, a soldier in the Indian Army, lives in a village with his wife Seetha and son Ramu.

Ganganna prevents workers from tilling Lakshmi's land so Raja helps her by hiring a tractor and completing the work.

Raja saves Lakshmi from an attempted molestation by Rangan and discovers she is his deceased superior's daughter.

The physician treating Ramu recommends he be taken to an ear, nose, and throat specialist in Madras, who advises psychological treatment but the psychologist is unable to offer a solution.

Raja becomes dejected; after being robbed by a passerby, he attempts suicide with his son but both listen to a prayer about Krishna, reconsider and return to Lakshmi's village.

The Tamil teacher, searching for Ramu, enters the house and sees Ganganna, who earlier cheated on his daughter, leading her to drown herself in a well.

Before the fire can engulf her, Ramu suddenly regains his speech and shouts at Lakshmi, who awakens, and they safely evacuate.

Saravanan learned the Hindi film was Door Gagan Ki Chhaon Mein (1964), and Chinna Menon, the manager of AVM's Bombay branch, told him it was unsuccessful but he was convinced the story was different.

Krishnan–Panju detested the film and Seetharaman believed a film featuring a child in a prominent role could only succeed if the child had powerful dialogue, evidenced by the success of AVM's Kalathur Kannamma (1960), whereas the boy in Door Gagan Ki Chhaon Mein is mute.

[10][11] Though Murugan, Kumaran and Saravanan planned to cast Jaishankar, who they felt was the right person to subdue the dacoits onscreen, Meiyappan felt Ganesh could better convey the character's grief for his wife's death and his son's loss of speech; they agreed with their father's choice of Ganesh.

[15][16] The climax scene, depicting Ramu and Seethalakshmi in a burning room, was filmed over five days; kerosene was used to light the fire.

[2][3] After R. G. Gope edited the film, the final length was 4,272 metres (14,016 ft), amounting to 149 minutes.

[21][22] During the recording of this song, the original singer was unable to match the "weighty" singing of co-performer Sirkazhi Govindarajan, so he was replaced with T. M.

[12][25] Kalki appreciated Tirulokchandar's direction, Seetharaman's writing, and called Ramu a pleasing family film.

[12] His brother Ashok appreciated Seetharaman for making "suitable changes" that made the Tamil film more successful.
