Ying Xiong Wei Lei/Heroes Shed No Tears(1986) was a pivotal feature in the early 80s for the director, John Woo. This was the first John Woo movie that included heavy use of gunplay. Although filmed in 1984/85, Heroes Shed No Tears(1986) did not get released until after the box office success of A Better Tomorrow(1986). Before this, Woo was mainly known for his comedies and Kung Fu flicks. Heroes Shed No Tears(1986) combines explosive action with some good martial arts.
Even if the film isn't as great or polish as John Woo's best, its still better then most of the ones that he has done in Hollywood. There are a few terrific set pieces within the movie. One, the opening gun battle with some drug runners. Two, the fight between the mercenaries and the Thai natives. Three, the martial arts fight between Eddy Ko and Ching Ying Lam.
It was one of the few war films besides Eastern Condors(1987) and Bullet in the Head(1990) to come out of Hong Kong. Ying Xiong Wei Lei(1986) is a precursor to John Woo's Bullet in the Head(1990). The plot of the film is very similar to Eastern Condors(1987) in that both films deal with mercenaries who are sent to Southeast Asia on a secret mission. Heroes Shed No Tears is the most grim and nihilistic of all John Woo movies(that includes Bullet in the Head). Its in the tradition of films like Aguirre:The Wrath of God(1974), The Deer Hunter(1978), and Apocalypse Now(1979).
Heroes Shed No Tears(1986) is a modern day retelling of the Lone Wolf & Cub comics. The relationship between Eddy Ko's soldier and his son has the same fatalistic bond that was present with Ogami Itto and his son, Daigoro. Its the closest thing that John Woo has ever come to doing a Lone Wolf & Cub feature. There is a scene that's right out of Lone Wolf & Cub(involves a child who covers himself in a mudhole in order to avoid being burned alive in a fire). The big influence for the one sequence is a similar sequence from Lone Wolf & Cub:Baby Cart in Peril(1973).
Ching Ying Lam is very convincing as the cruel and sadistic Vietnamese officer. The torture scene involving Eddy Ko is the most brutal one ever done by Woo. Heroes Shed No Tears(1986) has many traits that would become part of the Heroic Bloodshed genre in Hong Kong. Has its share of fogish atmosphere and stylish cinematography. The fight near the end of the movie would be done again in the terrible Mission:Impossible 2(2000)(there was also a exact scene in Strike of Death{1975}).
