Thalaikoothal (English: Taking complete bath, including head, தலைக்கூத்தல், and also means Senicide - killing elderly people) is a 2023 Indian Tamil-language neo-noir drama film directed by Jayaprakash Radhakrishnan and starring Samuthirakani, Kathir, Vasundhara Kashyap, Baby Vishrutha and Katha Nandi in the lead roles.

[1] Pazhani is a middle-aged man who lives with his wife Kalaiselvi and daughter and cares for his bedridden, comatose father Muthu.

His father-in-law suggests performing Thalaikoothal on the ailing father since he's been comatose for so long and is now a burden to the family, to which Pazhani strongly disagrees.

The film progresses in a non-linear fashion with intermittent flashbacks from Muthu's youth, when he was in love with a lower caste washerwoman girl Pechi.

They give him an oil bath, make him drink coconut water, and put him to sleep on the floor overnight as per the standard procedure.

Pazhani and his family relocate to the city to pursue his work when his daughter confronts him inside the bus about the Thalaikoothal incident, which she discovered from her friend.

Jayaprakash Radhakrishnan who earlier directed Lens began working on the project by early 2021, revealing that he had started a "village-based" film during an interview in March 2021.

Bhuvanesh Chandar from The Hindu wrote that the film was "simply outstanding", adding that "Jayaprakash’s poignant drama about a son’s fight to save his comatose father has brilliant performances, unbelievably great sound design, and stunning visual imagery that speaks of the value of a life".
