In "Iron Face Selflessness", the director proficiently used film techniques to vividly show the gang events that occurred in the 1930s to the audience. The atmosphere of "Iron Face Selflessness", the scene arrangement and costume design are filled with a strong atmosphere of nostalgia. In the film, the gentlemanly demeanor between the various characters' gestures is at a glance. Sean Connery has a wonderful performance in the film. Under his interpretation, the shot of the male protagonist crawling after being shot has become a classic in movie history. And Robert De Niro's performance is also very wonderful, he explained the tyrannical tyranny of the gang boss in the film.
The director of the film is unique in that it creates intricate contradictions and conflicts for the film. In the shootout between the life and death of the detective and the gang leader, the director and screenwriter jointly create a strong dramatic conflict. In the waiting hall, with the help of a baby carriage pushed by his mother, the director pushed the scene to a tragic climax that moved people's hearts. The baby stroller with a small weight is like a weighing scale, which makes the shootout even more exciting. This detailed setting binds the opposing parties together like a super glue, and the original plane line between the two parties becomes a three-dimensional and multi-dimensional dramatic space. In addition, this detail also aroused the audience's worries about the fate of babies and mothers, which caused the psychological effect of "heart hanging in the throat". Through this scene, the choreographer weaves a puzzling "serial link", which not only fascinates the audience, but also increases the audience's desire for discovery, and at the same time makes the film more humane.
