Baba is a 2002 Indian Tamil-language supernatural action film written and produced by Rajinikanth under his banner Lotus International, directed by Suresh Krissna, with cinematography by Chota K. Naidu. Along with Rajinikanth in the title role and Manisha Koirala in the female lead, the film features an ensemble supporting cast. Amrish Puri makes his appearance in a Tamil for the second and final time after Thalapathi (1991). The original songs and background score were composed by A.R. Rahman.


The film opens with the birth of Baba (Rajinikanth), who is the reincarnation of a saint that was a devotee of Mahavatar Babaji. Baba grows up as an atheist and hot-blooded man, but becomes a good samaritan with his thoughts and actions. His lifestyle includes consuming alcohol, smoking beedi, and chewing tobacco. His mother (Sujatha) and maternal uncle (M. N. Nambiar), for whom Baba has great respect and love, are ardent devotees of Mahavatar Babaji. Chamundeswari (Manisha Koirala) stays in the neighbourhood of Baba's residence which often quarrels with Baba but eventually falls in love with his style and attitude.
