Browning especially likes to frame his characters against doors and windows, as well as wall hangings and pictures. The vertical lines of these doors and windows dominate his compositions. Usually the vertical lines extend from nearly the top to bottom of his composition frames. Most of the sets of the picture look spacious - one feels there is always a lot of space for the characters to move in. No one ever looks hemmed in.
Browning includes two action scenes in the film, one toward the beginning, and one at the end.
Perhaps it is just me, but I found them hard to follow. In the final melee, for example, I couldn't tell who was battling whom among the various fighting pairs. Several of the scenes look as if they were shot on the streets of San Francisco. It is hard to tell if the opening Chinatown scenes were actually shot in San Francisco's real Chinatown, or whether the streets are studio recreations. The film is completely sympathetic to and respectful of its Chinese characters.
