One of the earliest western action films that Chinese people came into contact with, the scene of opening the envelope explosion is still fresh in the memory, the middle part is slightly dull, and a large-scale action scene at the end pulls the audience back into view. Now it seems that this film is the scale of B-level film, but B-grade film has always been simple and direct, not muddy, although the action scene is not too large-scale, but it is enough to attract the attention of the audience. In the early years, I saw the big screen twice at work, and the visual effect was quite good. Later, I saw it again on TV, but it is a pity that the Mandarin of that year has now been lost.
