Popular Australian film star Chips Rafferty made his screen debut in 1940's Ants in His Pants.But you'll have to look hard for Rafferty, for his is a very minor role in this musical comedy-drama. Will Mahoney stars as a small-time carnival worker whose girlfriend's kid sister (Jean Hatton) needs a throat operation. To do this, Mahoney enters the boxing ring, despite his inexpertise in pugilism. Miraculously Mahoney wins the bout, and the little girl is able to belt out the film's closing tune. Ants in His Pants was released in the US as Come Up Smiling. ~ Hal Erickson, Rovi
