M. Kumaran Son of Mahalakshmi

For Kumaran (Jayam Ravi), life revolves only about his mother Mahalakshmi (Nadhiya), who got separated from her husband Easwar (Prakash Raj). Easwar goes on to pursue his passion in kickboxing and becomes a world-renowned trainer based in Malaysia. Mahalakshmi stays in Chennai and devotes her life to bringing up her son. Kumaran is also passionate about kickboxing and shares a special relationship with his mother. In between, he falls in love with Mythili (Asin), a Malayali girl, but his life is destroyed after his mother's death. On her deathbed, she tells him to meet Easwar, and Kumaran goes to Malaysia to meet him. Kumaran gets a job at his father's kickboxing academy but finds him with another wife, Shalini (Aishwarya), and a daughter Swapna. Kumaran feels betrayed and angry, and this causes plenty of friction between him and his father. Eeshwar trains a boxer named Anand (Subbaraju), who he is sure will win the championship. Easwar considers Anand his protege and, on many occasions, demonstrates his preference for him over Kumaran. However, Anand soon makes Swapna pregnant and dumps her. Kumaran find this out when he follows his step sister and step mom to a pet store, where they are purchasing mosquito repellent to ingest and die. The stepsister is planning to drink the mosquito repellent in hot milk to kill herself and her potential fetus. He then turns traitor to Easwar and joins another team when they offer him a better contract. The rest of the story is about how Easwar trains Kumaran against Anand and wins the kickboxing competition, while Kumaran helps his half-sister with her love. Kumaran wins the kickboxing championship. The movie ends with Kumaran seeing a final apparition of his mother looking at him proudly and waving goodbye.

After the success of Jayam (2003), Raja decided to remake the successful Telugu film Amma Nanna O Tamila Ammayi (2003) with his brother Ravi in the lead role. Asin, who appeared in the Telugu version, made her debut in Tamil cinema with this film. Nadhiya made her acting comeback with this film portraying Ravi's mother as Raja felt that he wanted to portray her as a modern mother as opposed to the usual portrayal of mothers, and she was the right choice for the role.[4][5] Prakash Raj, Subbaraju, and Aishwarya reenact their roles from the Telugu film.

The team had also initially approached Dhruv, the son of actor Vikram, to star as a child artiste in the film, but he eventually did not feature.[6]

The film was originally titled M. Kumaran S/O Bhagyalakshmi before reverting to the original title.[7] The film was extensively shot in Malaysia.

The songs and background score was done by Srikanth Deva.[8] The song "Ayyo Ayyo" is based on the Malaysian song "Hati Kama", composed by Pak Ngah.[9] The song "Chennai Senthamizh" is based on "Chennai Chandrama" from the original, which in turn is based on "Mahaganapathim" by Muthuswami Dikshitar, and is set in the raga Nattai.[10]

The television satellite rights of the film were sold to Sun TV and VOD rights to Amazon Prime Video.[11]

The film collected share of ₹54 crore in 40 days in Chennai[17] and ₹36 crore throughout Tamil Nadu selling $3 million tickets.
