Debt) is a 1980 Indian Hindi-language romantic thriller film directed by Subhash Ghai, starring Rishi Kapoor and Tina Munim in the lead with Simi Garewal in the critically acclaimed role of Kamini Verma, the murderous wife, which won her a Filmfare nomination.

Ravi calls his widowed mother (Durga Khote) and younger sister (Abha Dhulia) to share the good news and that he is marrying his girlfriend, Kamini (Simi Garewal), who is actually a gold-digger working for Judah, unbeknownst to him.

Tina tells him that she was brought up by a woman she addresses as Rani Sahiba, and her uncle, Kabira (Pran), who is released from prison after having served ten years for murder.

Kabira then reveals to Monty that Tina's father was murdered by Kamini's brother after overhearing a secret involving Ravi and the temple of Kali.

In their final trick, Monty and Tina perform at a local school opening function attended by Kamini, where they dramatise Ravi's story.

[8][9] Despite being counted as a cult classic today, Karz was declared an "average" nationwide during its opening and very next week Feroz Khan's mega budget Qurbani was released and crashed it at the box office.

Though the theme of reincarnation was earlier handled in Madhumati (1958), Kudrat (1981), and Mehbooba (1976), the modern twist with the murder and revenge angle in Karz was a contemporary pot-boiler.

[12] Director Subhash Ghai admitted that Karz was partly inspired by the 1975 film but was mixed in with Indian beliefs on reincarnation.

[5] Karz went on to inspire several other Indian remakes, notably Yuga Purusha (1989) in Kannada, Enakkul Oruvan (1984) in Tamil, Aatmabalam (1985) in Telugu, Baazi (1999) in Odia, Main Ek Din Laut Ke Aaunga (2007) in Pakistan, and the Hindi film Karzzzz (2008), starring Himesh Reshammiya.
