Some of these pictures and descriptions may give away plot details that you might not want to know before watching the film.
This is a Shaw Brothers Hong Kong martial arts movie. Unfortunately, there are no living lizards in it, but it gets credit for the title, at least. A thief known as "The Lizard" is a cat burglar who dresses in black and climbs walls and roofs without being seen. He only robs wealthy foreigners and he gives the money to the poor. He leaves a red toy lizard at the scene of a robbery to advertise who done it. He also kicks ass Kung Fu style and gets romantically involved with a girl who can also defeat most men with one punch or kick. Together they fight corrupt govenment officials and the mob.
