Monkey Doll) is a 2017 Indian Tamil-language crime thriller film, written and directed by Nithilan Saminathan in his directoral debut.

The film stars Vidharth, Delna Davis, and Bharathiraja, while Elango Kumaravel and P. L. Thenappan play supporting roles.

The music was composed by B. Ajaneesh Loknath with cinematography by Udhayakumar and editing by Abhinav Sunder Nayak.

On learning about Sundaram's association with Ekambaram, Viji's father rejects the proposal and insults him.

Meanwhile, Kathir, who has returned to Chennai, is waiting at a bus stop and sees a middle-aged man carrying a bag with a picture of a monkey on it.

Kathir's mother phones him telling that Sundaram came to Chennai two days ago and has not returned home.

One of Ekambaram's henchmen is seen buying the bag, for smuggling a golden idol worth 5 Crore from Thanjavur to Chennai.

On arrival he is met by Sadhasivam (the man from whom Sindhanai stole the bag at the bus stop), one of Sekar's aides.

Sekar asks Sundaram for his forgiveness as he desperately wants the money to give his wife and children a wealthy life.

Kathir gets a call from one of Ekambaram's henchmen, who saw the Facebook post about the bag and assumed that both father and son have been scheming all along to steal the idol.

Nevertheless, the henchman orders Kathir to get the bag back to him within an hour's time and meet them at Sekar's house.

As the camera pans out, Sekar is shown to be a quadruple amputee who now lives a life filled with regret for all the wrongs he committed.

Nithilan rose to fame after participating in the reality show, Naalaya Iyakkunar short film competition on Kalaignar TV.

[12] Further positive reviews came from Sify.com, who called it "a well-made crime thriller" and The New Indian Express, who noted it was "another efficient film from Vidharth's stable", making a reference to his two previous critically acclaimed films, Kuttrame Thandanai (2016) and Oru Kidayin Karunai Manu (2017).

[13][14] The film performed well at the Chennai box office, with positive word-of-mouth reviews, making it have a better response than Vijay Sethupathi's Puriyatha Puthir (2017), which released on the same day.

Baradwaj Rangan of Film Companion wrote "Like Maanagaram earlier this year, Nithilan Swaminathan's Kurangu Bommai (Monkey Doll) comes with a caveat: you have to buy the coincidences.
