Odd Couple (Chinese: 搏命單刀奪命搶) is a 1979 Hong Kong martial arts comedy film directed by Lau Kar-wing.

[1] The film initially focuses on two rival martial artists who have a tradition of annual duels with each other, in a futile attempt to decide which one is the best.

Facing the effects of old age, the two rivals decide to train replacements to continue their annual tradition.

Every year the fight ends in a draw, and as the masters are getting old, they decide the best course of action is to each take on a student to determine who is the better teacher.

A previously upright martial artist known as Old Yellow Dog (Bryan Leung) kidnaps the students (also played by Lau and Hung) before their duel can begin.

Now, after years of training in the long bladed staff and with a new name, Laughing Bandit, he wants to lure the old masters out to exact his revenge.

After another long competition, the film ends with the pair laughing at the absurdity of the rivalry and realising that as friends they will never be able to determine who is the best.
