Fatal Bet is a 1989 Hong Kong action drama film written and directed by Jimmy Heung and Kin-Nam Cho (as Dick Tso).

Soon after being released from a Hong Kong prison, professional gambler Crab and his friend Sam are summoned by a tycoon named Dragon to his casino in Lake Tahoe to crack a baccarat scam being run by the half-Chinese and half-Japanese Taro and his father Gubon, head of a powerful Japanese syndicate.

Crab instead offers to play against Taro himself for a bet of half a million dollars, but the police unexpectedly break in.

Catherine bets all of her assets of $50 million, which Gubon cannot match, so she also requests the left arm and leg of Taro.

Taro does not want to cut off his arm and leg, so he shoots and kills his father and other audience members before being shot dead by both the Americans and Japanese.

Fatal Bet is based on the same true story as Heung's film Casino Raiders and has virtually the same plot.

Heung decided to use a budget of HK$8,750,000 to direct two versions of the story, one in Cantonese and one in English for international audiences.
