Karpukkarasi is a 1957 Indian Tamil-language swashbuckler film directed by A. S. A. Sami and produced by M. Somasundaram under Jupiter Pictures.

One scene required Ganesan to throw a knife at Nambiar.

He did so, but the director had not called for "action" when Nambiar saw something come straight at him like a "bat out of hell".

Nambiar had only one second to turn his head as the knife grazed his eye and impaled itself on the wall, leaving Nambiar with a permanent black spot on the eye.

Ganesan had thrown the knife long before the shot was supposed to roll, only to impress two women who had walked on to the set.
