Kusthi is a 2006 Indian Tamil-language comedy film directed by Raj Kapoor, starring Prabhu and Karthik, while Vadivelu, Manya, Flora, Vijayakumar and Radha Ravi play supporting roles.
The movie begins with Jeeva (Prabhu), running away from his village to Chennai fearing a possible marriage with the daughter of a local chieftain (Radha Ravi), arranged by his father.
Meanwhile, he saves a youth (Mahanadi Shankar), a henchman of a local goon Singam (Karthik) from some gangsters.
However he manages to win the heart of the family members and they arrange for Jeeva and Singam's wedding with Vijayakumar's grand daughters Abi and Divya.
It is nothing but a mish-mash of mistaken identities, slapstick comedy, a bit of glamour, a comic villain, loving grandfather, mother sentiments and lots of crass jokes".
The film, which brings together Prabhu and Karthik after a long gap, is weak on logic and weaker on laughs".
