This is an underrated film that has received reviews too dismissing, I feel. I agree with the above reviewer on some of its shortcomings, but would also point out that there is a very nice tension set up between Gene Tierney and Lynn Bari throughout most of the story which certainly had me watch it through to the very end. Contrary to other opinions, Tierney fans will not be disappointed here, although I agree she doesn't truly shine as in some others; and Lynn Bari is at her best and definitely makes us wish she had been given more prominent parts. Some feel that Bari actually makes this movie, but this may be going too far. Moreover, I don't believe China Girl was ever intended as a war movie per se, rather a drama. The war-scene ending just happens to be the bitter twist that closes what is essentially a war-time drama between a guy and two gals it's no more complex than that.
Also, the camera is no slouch either, in this movie. It has excellent shots in the hotel rooms where much of the action takes place, giving it a somewhat noir feel that definitely generates an overall stylish period polish that is in synch with the true noirs of the period. If you like this style, as I do, China Girl is worth seeking out. One can only hope that it will eventually become part of a Tierny Collection. I'm certainly keeping my fingers crossed!
