Mankaatha is inspired from Hindi movie Jannat!!! True?

No. Fortunately it is nothing at all, I repeat at all like Jannat. There is hardly
any talk about cricket betting. Don't worry.

Mankatha is waaaaay classier and original than Jannat, nothing in common between the two!

Jannat is a remake from the Malayam flop film Yaar Yndhe Penkuitylea (Onde amma).

Manaktha is based on a a person who name is Vaiyepothu Kosu aka Pardesi. Who was a Don/gamler in Chennai during Korango war.
