Vaathi" is a Tamil language song from the Indian film "Master," released in 2021. It was composed by Anirudh Ravichander and performed by Anirudh and Arivu. The song became incredibly popular and gained widespread recognition, reaching a large audience both within and outside of India.

However, "Vaathi" itself is not the title of a movie, but rather a song from the film "Master," directed by Lokesh Kanagaraj. The film stars Vijay and Vijay Sethupathi in the lead roles and revolves around the intense rivalry between a college professor and a criminal mastermind. The movie explores themes of power, corruption, and the battle between good and evil.

While the song "Vaathi" was a massive hit and received significant attention, it is part of the larger movie "Master."
