This is a well made adventure film that is also a character study. It's a top of the line production from Robert Wise. The photography by Joe MacDonald is impeccable, the acting with the exception of non actor Candice Bergen is of a high caliber. The screenplay from the playwright Robert Anderson, has been carefully worked out. The Sand Pebbles is also a very long film.
Wise really hit the jackpot in 1965 with The Sound of Music which in someways was kind of his undoing since he never achieved that large commercial success during the remainder of his career. The Sand Pebbles was the film Wise actually wanted to make before The Sound of Music, but the pre-production of this film was so long and difficult that Wise used his downtime to film The Sound of Music instead.
The film is set on an American gunboat patrolling the Yangtze river in the 1920's. The purpose of these river patrols were to protect American interests in China. Since the film was made during the Vietnam War and Robert Wise was a good Hollywood liberal, there are some minor criticisms of the United States involvement in Asia that are clearly a reference to Vietnam.The Sand Pebbles is essentially a film from the well crafted "they don't make them like this" school of film making.
182 minutes (I think) the roadshow version was 196 (whew). Written by Robert Anderson.
