Goodman to the good) is a 1984 Indian Tamil-language action drama film, directed by S. P. Muthuraman and produced by AVM Productions.

A remake of the 1983 Telugu film Dharmaatmudu, it stars Rajinikanth and Radhika, with Karthik, Thulasi, V. K. Ramasamy, Major Sundarrajan, Y. G. Mahendran and Visu in supporting roles.

The screenplay of Nallavanukku Nallavan was written by Visu, who made minor changes to differentiate it from the Telugu original, which co-producer M. Saravanan noticed was very similar to the unsuccessful Tamil film Hitler Umanath (1982).

When Gangadharan becomes bankrupt, he plans to close Victory Industries as he is unable to repay his debts to money lenders.

After watching the Telugu film Dharmaatmudu (1983), director A. C. Tirulokchandar told M. Saravanan of AVM Productions about his desire to remake it in Tamil; he wanted Rajinikanth to play the male lead.

[9] Muthuraman believed it would be innovative to see a heroic actor play a negative character, so he approached Karthik for the role of Vinod.

He initially refused as he was not interested in portraying a negative character, but after Saravanan promised to cast him in a heroic role in a later film (which would become 1985's Nalla Thambi), he agreed.

[4] One scene in the film involving a strike was based on a real incident which happened at TVS Motor Company.

[9] For another scene, picturised on Rajinikanth and Karthik and shot at AVM Studios, Babu lied on a bed-sheet spread over the floor to film it from a new angle.

[5] While watching the double positive,[a] he was dissatisfied since Nallavanukku Nallavan was primarily an action film and felt a gentle climax would not be suitable.

[20] It is set in Shivaranjani, a Carnatic raga,[21] and marked playback singer Manjula Gururaj's debut in Tamil cinema.

[26] On 26 October 1984, The Hindu in its review wrote, "Muthuraman has a large hand in embellishing the dramatic elements with deft touches and polished handling".

[1] Despite facing competition from other Diwali releases such as Vaidehi Kathirunthal and the Tamil-dubbed version of the Malayalam-language My Dear Kuttichathan,[27] the film was a major commercial success, running for over 150 days in theatres.
